MUSIC IN CULTURE – HISTORICAL AND GEOGRAPHIC APPROACHES
Perhaps the most important task which ethnomusicology has set itself is the study and discovery of the role which music plays in each of man's cultures past and present, and the knowledge of what music means to man. Although an interest in this task is professed by most participants in our field, there is as yet little agreement and little standardized theory regarding the procedures to be followed in pursuing this interest. Ethnomusicology can not, of course, claim credit for alI scholarly interest in musical culture, for the historians of Westem music, the psychologists and sociologists of music, the folklorists and philosophers, and others, have also explored it. But ethnomusicology brings to the study of music in culture the points of view and the methods of anthropology, varied though these have been, and ethnomusicologists are the only large group of scholars who claim an interest in all aspects of musicallife, in alI cultures, individually and in groups.
Nevertheless, they are only at the beginning of their work, and what they have accomplished so far cannot be summarized or outlined. This chapter and the next, rather than attempting to give a thorough exposition of alI that has been done, present a selection of the most influential and most promising theories and studies. In these chapters we are interested in 1 ) the role which music plays in human culture and the ways in which this can be studied, and 2) the methods and theories by which music has been-and can be-approached in ways similar to the ways in which other aspects of
culture are approached by anthropologists.
It seems to be most convenient to divide the study of music in culture into two broad areas: the study of the individual group, or person, or nation in one place and at one time; and the study of music in its spatial (i.e., geographic) and temporal (i.e., historical) environment. The first of these areas would seem to be a prerequisite to the second, but as is so often the case in a young discipline, the broader and more difficult questions have been broached before the narrower and perhaps less obviously fascinating ones. Thus there is much more theory and method available on the study of change in music, and on the geographic distribution of music, than there is on the study of music's role in one culture or in one person's life. Studying the geographical distribution of musical phenomena and the ways in which music changes, and participates in culture change, is important to an understanding of the role of music in culture. It may seem that representing the distribution of musical style traits on a map, for example, has nothing to do with other aspects of culture.
But doing so might, for example, perhaps enable us to show how this distribution coincides with that of cultural or linguistic features, and how it is associated with them. It could tell us something of the way in which music was affected by the movement of peoples from country to country, and it might show something about the past associations of neighboring or distant peoples. By studying change in music we are approaching music as anthropologists would approach other aspects of culture, and in this way we are also learning about music as a phenomenon of culture. We shall devote ourselves, in this chapter, to a consideration of the historical aspects of the study of traditional musics (especially where no written records are available), and to the problems and significance of studying the geographic distribution of musical styles. These are two different matters with which we will deal separately, but which are in some ways closely related and interdependent.

Origin and Change
In spite of the variety of materials and aims, the historical aspects of ethnomusicology can be grouped into two principal classes – origin and change. Explanation of the origin of various phenomena has been at the root of many developments throughout our field, and until recently it predominated over the study of change. But while the study of origins has in a sense been exhausted or in many cases seems impossible to pursue further, the study of change promises to be of even greater interest when some methodological problems have been solved.
The problem of origin can be approached in a number of ways. For example, one may be interested in the manner of origin of a given phenomenon, or in its place of origin. The manner – of – origin approach has been one of the more speculative sides of ethnomusicology, and has provided considerable common ground between our field and historical musicology. The problem of the origin of music itself falls into this class, although ethnomusicological data can only corroborate or, more frequently, negate. Nevertheless, some theories of the origin of music which indicate the special function of music in non literate cultures and its close ties to religion are genuinely based on anthropological information (for a summary see Nadel 1930).
The search for the manner of origin of various generalized musical phenomena is also involved here. For example, the debate on the origin of polyphony carried through the decades (e.g., Adler 1908, Lachmann 1927, Schneider 1934), the arguments for single versus multiple origins of polyphony, the discussion on the possibility of various types of polyphony developing separately or together, would all be included in this category.
Slightly different is the treatment of specialized or localized musical phenomena. The origin of certain types of scales and meters is relevant here, insofar as the approach does not stress the development of one type from another; the latter should probably be covered in our "change" category. An example of this approach would be the investigation of the origin of the anhemitonic pentatonic scale: whether it was derived acoustically through the circle of fifths, through the repetition of a two-tone motif at different pitch levels, or through filling gaps in or melodic sequence, which may be interpreted as variety introduced in a repetitive musical structure, or (since it is most frequently downward movement) as repetition modified by the prevailingly descending melodic contour of music(Kolinski 1957 :3), or in still other ways. It would be difficult to exhaust the examples of the manner – of – origin quest in ethnomusicology for it may be justly said that it has provided the impetus for a large proportion of the research in this field.
The search for the place of origin of musical phenomena, generalized and specialized, has pinpointed a number of problems in ethnomusicological method. The place of origin of medieval European polyphony (summarized by Reese 1940 : 249 – 58) of the styles of some Northwest Coast Indians (Barbeau 1934) of certain musical instruments, and even of individual compositions such as the folk songs in European traditions, to cite only a few examples, have produced a variety of studies and theories.
The general problem of place of origin has been approached from the nonmusical side as well. Musical materials have been used to ascertain the possibility of cultural contact among widely separated peoples, and it is in this area that the historical orientation of ethnomusicology has made its greatest contribution to cultural anthropology.
The problem of change, although often related to and combined with the problem of origin, requires somewhat different approaches. We are interested in the reasons for change
(or for lack of change), and in its nature. degree, and rate. This applies to various levels of musical organization. We can study the change in individual compositions or in larger bodies of music. We can try to trace the changes indicated by differences among the variants of a single song, and we can try to identify the reasons for them, whether these lie within the structure of the music or in its cultural context. We can try to measure, for comparative purposes, the amount of change that has taken place and try to determine how rapidly it has occurred. Similar matters can be studied – but with greater difficulty – in entire repertories, whether defined geographically or by their cultural milieus. If more than one composition is involved, statistical methods are usually drawn upon. Finally, investigations involving change are frequently associated with those concerning the place of origin of a musical phenomenon, for the obvious reason that if a musical item moves from one place to another, it is also subject to change, and it would be impossible to assess the change without considering the geographic movement.
It is useless to try within a short space to survey all of the studies in ethnomusicology involving historical perspective. However, the approaches of several of these studies are summarized in the following pages, and we will attempt to give examples of the general conclusions to which they have led, and to formulate some of the general tendencies which seem to prevail.

Problems of Origin
The origin of music, as well as of individual musical phenomena, has usually been explained by reference to three possible processes. It may be a coincidence based on the structure of a related phenomenon, it may be motivated by a nonmusical need, or it may be inevitable through some process of evolution – so say these theories, summarized by Kunst (1959:46-8). Thus, the origin of music in emotional speech (a theory not widely accepted) or in vocal signaling over a long distance (one more widely held) could be based on coincidence. A human need for music, and its resulting invention, are postulated in theories involving rhythmic work and religion as the cradles of this art. Music as a human version of mating calls, or as a specialized form which developed from a pre-language and pre-music generalized type of communication (Nettl 1956:136) are examples of evolutionist views.
Most origin theories involving smaller – scale phenomena are also based on one of these three approaches. For example, most forms of polyphony are attributed to discovery by coincidence or by faulty rendition of monophonic materials. This point of view does not explain why “faulty” rendition (e.g., singing of two variants of the same piece simultaneously, or overlap in antiphonal singing, or singing the same melody at different pitch levels) should in some cultures lead to the development of polyphonic music, while in others it is simply written off as error. The origin of some instruments is also attributed to coincidence – for example, the origin of the musical bow from the hunting bow.
It is also possible to postulate the development of musical features in some styles on the basis of aesthetic needs. The need for unifying factors in orally transmitted music may bring unity in one element in order to balance the elaboration or heterogeneity in another. It is possible, for example, that a style in which tonal material is being expanded (over a period of years or centuries) will also introduce the melodic sequence in order to offset the diversification. Or a style based largely on repetition of short melodic formulae may introduce and encourage improvisation and variation in order to offset the large degree of unity. This view is supported by the complementary distribution of the unifying elements in some styles of music.
The evolutionist view is represented by such hypotheses as that the direction of musical change remains constant; so, pentatonic scales naturally develop from tetratonic scales if the latter have in turn developed from tritonic scales. The opinion that there are stages through which all musical cultures inevitably pass is, of course, also pertinent here.
The problem of single versus multiple origin has occupied ethnomusicologists on many occasions. On the whole, they have adhered to the generally accepted anthropological viewpoint, using geographic distributions and assuming that the likelihood of multiple origin decreases with the complexity of the cultural feature whose origin is being sought. They have also used data from acoustics (Hornbostel 1910) to explain the presence of the same phenomenon in widely separated areas. The main problem faced here by ethnomusicologists is the measurement of degree of complexity and similarity. The problem is shared with cultural anthropologists, but it is somehow more specialized here because of the peculiar structure of music. It is possible, after all, that musical material, being in structure relatively independent of other cultural elements and being easier than other features to describe and analyze, is better suited to measuring than are some other cultural phenomena (Merriam 1956: 465).

Problems of Change
Why, how, and under what conditions does music change? Although these questions have not been answered with scientifically predictable results for any one type of music, they have considerable significance even for material outside the scope of ethnomusicology, as have the converse questions regarding the identification of stability and of stabilizing factors in music.
It is first necessary to define musical change. In traditional music, change seems to be a phenomenon substantially different from change in a high culture. While changes through substitution in a repertory occur in both kinds of culture, it is only in those cultures which make use of oral tradition that established compositions are altered. (Of course, changes in performance practice of written music also must be considered in high cultures). Thus, change in a fine art tradition tends to be cumulative, new material simply being added to the old, while the old remains at least to a 'degree part of the heritage. In an oral tradition it may be change in a more profound sense, old material being eliminated as new material is introduced. Changes in a repertory, or beyond the simple alteration of the individual compositions, occur in various ways. Individual elements of music may undergo change, while others remain the same. New songs may be introduced into a repertory, causing the older material to change by assimilation; or the new material may gradually change to accommodate the style of the old.
Changes in a repertory, if not caused by the substitution of new compositions for older ones, are of course determined by the changes wrought in individual compositions. But when change in a repertory is evident, it is often impossible to determine what has happened to individual compositions. Thus the two levels of change must usually be approached in contrastive ways.
There are many reasons for musical change, and the following discussion is limited to those involving music in oral tradition. However, the same reasons, and perhaps others, may be relevant to cultivated music. We are not in a position to assert under what conditions, how fast, and how much music changes, and which aspects are most subject to change. It is possible to divide the approaches of scholars to change into two main classes: those which make use of strictly musical (or aesthetic) criteria and concern themselves with the characteristics of the musical material itself; and those which make use of nonmusical criteria, including cultural and racial ones. Of course, these approaches are not mutually exclusive; both must be used, and which one is finally preferred depends on the individual case.
The first to be generally accepted were racial criteria. These were partially subscribed to by such men as Carl Stumpf, E. M. von Hornbostel, and Marius Schneider (1946).Today they are not generally accepted; but they have been the subject of technical investigation by Metfessel (1928) and Bose (1952).
On the whole, racial approaches tend to concentrate more on musical stability than on change. The musical relationships among members of different racial groups are of course intertwined with cultural relationships, and to separate the racial factors is a difficult and sometimes impossible task. Nevertheless, statements have been made (e.g. Schneider 1938:290; Schneider 1957) that the style of music is determined by the culture, but the manner of performance, vocal techniques, and so forth, are determined by the racial background, and there have been attempts to associate specific musical traits with certain racially defined groups – cascading melodic contours with American Indians, for example.
Since members of a race have normally lived in close cultural contact, the existence of common musical traits hardly proves racial or physically inherited traits. Even when the characteristics of a racial group, such as the African Negroes, are brought from one place to another, such as from Africa to the New World, we have no convincing case for racially inherited musical characteristics.
The notion that members of a racial group tend to accept materials from physically similar groups more readily than from different ones seems too speculative. Moreover, it is negated by such cases as the distribution of individual songs through the various physical types of Europe, the influence of Arabic music on East African Negro music, and the relatively similar musical styles of Africa and Europe (viewed on a broad scale) as compared to the musical contrast between African Negroes and the physically similar Melanesians. The accompaniment of cultural influences by racial ones in many cases obscures the problem, and we must conclude that the racial approaches to musical change have not contributed much to ethnomusicology.
Among the many things which cause musical styles to change is the contact among peoples and cultures, and the movement of populations which is one cause of such contact. It is probable that most documented cases of changing repertories are due to culture contacts. Peoples living side – by – side influence each other, and where there is movement of populations the greater number of contacts increases the possibility of musical change. One might conclude from this that a tribe which moves about experiences greater or more rapid musical change than does one which remains among the same set of neighbors. The former tribe might also have a high rate of elimination of musical material; or, holding on to old styles as new ones are introduced, it might increase the total number of styles in its repertory. Thus we conclude that a tribe with many outside contacts may have more variety in its music than one with a stable and limited set of contacts. This approach is illustrated by a study of Shawnee music, in which we see that Shawnee contacts with other Indian tribes resulted in the introduction of new styles. The Shawnee around 1950 had music which could be traced back to their contacts with the northern Algonguins, the southeastern United States, and the Plains Indians. On the other hand, we find that the Pueblos have a rich and complex but rather unified musical style, perhaps because (at least in recent centuries) their contacts with other tribes have been limited. The generally conservative nature of Pueblo culture may also be involved here.
Another problem involving musical change through cultural contact is the direction of influence. This can generally be answered with some degree of certainty: the more complex style tends to influence the simpler one. This does not necessarily mean that the music of the more complex culture is introduced into the simpler one, for occasionally the (generally) simpler culture may have the more complex music. A variety of stylistic combinations may also occur, as indicated below in our discussion of acculturation. In these combinations, however, it seems likely that each culture contributes the elements which it has developed best or to the greatest degree of specialization. For example, the mixture of African and European styles found in Haitian music consists essentially of African rhythm, antiphonal singing, and drum accompaniment but European melodic structure, perhaps because the melodic aspects of music are more highly developed in European folk music than in African Negro music.
A musical style may move from one tribe to another without the accompanying movement of a tribe or people itself. This – can happen when songs are taught by one culture to a neighboring one, or when individuals move from one tribe to another, or from one country to another. The musical style which is thus moving is likely to change the repertories of the tribes or nations through which it passes, but it may itself also undergo change, influenced by the tribal styles with which it has made contact. For example, the Peyote style, as defined by McAllester (1949), presumably moved from the Apache and Navaho to the Plains Indians. It retained a feature of Apache music, the use of a restricted number of note values (only quarter and eighth notes are usually found), but in the Plains it evidently acquired the cascadingly descending, terrace – shaped melodic contour. Possibly the forces described above operated here: the melodic contour of the Plains, a specialized and well developed type, was strong enough to encroach on the Peyote style, but the more generalized rhythmic structure of the Plains was not strong enough to alter the specialized rhythmic organization derived from the Apache. Thus it may be justified to assume (although there are few documented examples) that specialized features in music are less easily changed than generalized ones, and from this to proceed to the hypothesis that generalized features are constantly undergoing change in the direction of becoming specialized. A specialized feature may be defined as one having a striking, overriding characteristic which allows little flexibility for the composer's imagination to provide original effects.
Movement of musical material occurs not only in large bodies of music but also at the level of the individual composition, where the same forces seem to operate. In European folk music it is possible to identify tunes which have moved through large areas. They seem rarely to have influenced the music of these areas to any great extent, but they themselves have changed for reasons discussed below ("The Role of the Individual Composition").It might be possible to infer that the larger a moving body of music, the greater is its influence on the repertories through which it passes, and the less it is itself subject to change.
Another force toward change may be called assimilation, the tendency of neighboring styles to become similar. While musical material which moves from one place to another influences the styles in its environment, there is also a force of attraction among the styles which are in constant contact. Thus, an area in which there is little contact among groups is likely to have diverse styles, but one in which the mutual contact is great is likely to have a more unified style. An obstacle to testing this hypothesis is the lack of measuring devices for degree of musical similarity. Yet it is possible to compare an area with much internal communication, such as Europe, with one in which communication is inhibited, such as Oceania, and find the hypothesis substantially borne out. Of course, the presence of other factors must also be considered here.
It is not possible to make decisions about musical change, its causes and directions, on the basis of strictly musical information. It is likely that certain directions of change do predominate and that one can in some cases, and with the corroboration of other kinds of information, decide such matters as the relative age of musical styles on the basis of structural features in the music. In most cases, music seems to move from simplicity to greater complexity (but not always!), so it is assumed by most scholars that the simplest styles are also the oldest. As indicated above, there may be movement from generalized to specialized elements – if it is possible to classify music in this way. Once a specific direction has been established, there may be a tendency to continue it for centuries. For example, if the tones in the scale of a song have been increased from three to four, further increases will follow, or at least a decrease will not ensue. These tendencies are speculative, and beyond the obvious simple – to – complex movement, they have not been used in specific investigations.
Other changes for which there are musical causes are related to oral tradition. Because there are mnemonic problems present in the oral transmission of music, the material must adhere to certain specifications in order to be retained. The music must be simple, and there must be unifying devices such as repetition, a drone or parallelism in polyphony, isorhythmic structure, repetition of a metric unit, a definitely established tonality, melodic sequence, the predominance of a single tone, etc. The necessity for the presence of such features tends to inhibit change, or to channel it. in specific directions. Thus, perhaps a melody with a rigidly isometric structure is free to become heterometric after having become isorhythmic. A melody with a hierarchical arrangement of tones, in which important and secondary ones are easily distinguished, may lose this arrangement after the introduction of sequences, since there is less need for the unifying function of the tonal structure. Again, these forces have not been studied in many examples; they are presented here as a possibility for future research. They can be observed in some European folk songs which have undergone change while passing from one ethnic group to another, but whether these changes are due strictly
to assimilation is an open question.
Measurement of the rate of change in music, and the amount of change in a given instance, awaits the discovery of proper methods. On the basis of impressionistic observation, particularly in the field of cultivated music, we may assume that change takes place irregularly; sometimes it is rapid or sudden, sometimes almost absent. In European music history there seem to be intervals during which musical style changes rapidly, while between them it changes only slightly over long periods of time.
Sachs (1947) believes that this is connected with the length of a person's productive life, and in effect blames it on the reaction of each human generation against its predecessor.
It Is often stated that the music of non-literate cultures must be somewhat-closer to the beginnings of music than is Western cultivated music, and that "primitive" music must therefore have changed more slowly. It is also possible that the rate of change is proportional to the complexity of the music. This may be due to the fact that where there are more features, more are subject to change. Or it may be caused by the more generally dynamic nature of complex cultures. Of course, the fundamental value system of a culture is also involved.
There is evidence that at least in some cases, music changes less rapidly than do other aspects of culture. Thus, most non-literate cultures which have had close contact with the West have taken on more European material culture, economic organization, and religion than music. Although reconstruction is difficult, there may be similar examples among the non-literate cultures which lack Western influence. The Apache and Navaho have possibly retained more of the northern Athabascan musical heritage than of certain other aspects of that culture. The Hungarians have retained some of the musical features shared by other Finno – Ugric peoples such as the Cheremis (Kodaly 1956: 23 – 59), but otherwise their culture has become Westernized.
The reasons for this slow rate of change probably vary with the example, and comparison of music with other cultural features is methodologically difficult.
There are two ways of studying individual cases of historical change in folk and nonliterate cultures and their music. One can try to reconstruct events of the past, or one can observe the changes occurring at the time at hand. The latter approach has been used in a number of cases involving acculturation (for example, Merriam 1955).The former has been used less often in cases involving individual repertories or styles (Nettl 1953, 1955b), but more often in general questions such as those involving the relative age of musical features.
For example, it has been used to reconstruct the history of European folk songs by comparison of variants. There are definite limitations to both approaches. The reconstruction method is limited by inadequate material and by too great reliance on speculation. The study of change in the present limits the amount of time during which change may take place, and involves specialized situations in which the cultures being studied are usually feeling the influence of Western civilization (Wachsmann 1961).

The Role of the Individual Composition
The individual composition must be especially considered in historical research in ethnomusicology. Its is a problematic role, for there is no clear – cut definition of what constitutes "a composition" in folk and primitive music, and this very lack accentuates the importance of historical orientation. Should one consider a group of variants with proved genetic relationship a single unit of musical creation? Most scholars would prefer this to a working definition of the single variant or rendition as "the composition," but they are then faced with the problem of proving the relationship. At the other extreme, one could devise melodic types which may or may not have internal genetic relationship, as has been done by Wiora (1953), and call these individual compositions without even considering the question of actual common origin. This would have the advantage of grouping similar materials and thus simplifying the picture. There are other possibilities, all of which show that isolation of the unit of musical creation is much more difficult in traditional than in Western cultivated music.
The problem of measuring degrees of similarity among different musical items has already been mentioned. It would appear that in some styles, all or most of the pieces are so similar as to be comparable to related variants of single compositions in other styles. For example, most songs of the Plains Indians appear, by virtue of their specialized melodic contour (terrace -shaped) and form (Al A2, with A2 an abbreviated form of Al) and by use of similar scales, as closely related to each other as the variants of a single English folk song found in several English-speaking countries. Thus the criteria used for one culture do not hold for others.
Informants' statements may be of help in some cases, and they have on occasion differed considerably from my own calculations.
Another problem is the identification or classification of musical items which, although composed at separate times, are based on each other or on a common model. In many cultures, the emphasis on originality (however one defines this term) is probably not as great as in Western civilization since about 1750, and there may be cases in which new songs are created simply by copying an already existing song with only slight changes. For descriptive purposes in all of these situations it is probably advisable to accept the informant's classification, but in comparative work this is usually not feasible.
The very existence of the problem of identifying individual units of composition points up some of the essential differences in historical change between cultivated and traditional material. In some non – literate cultures it seems that entire complexes of musical material are built up from a single composition. This process, described by Roberts (1933) and called by her the "pattern phenomenon," may occur, for example, when a ceremony unites a body of music which tends to become homogeneous by the process of intensifying the specialized elements of its style. In some cultures (Nettl 1954a:89), new material is consciously created from the old, either by elaborating songs already in existence or by combining material from several songs to form new units. The extent to which these products are individual compositions may also be questioned. To be sure, a similar problem occasionally appears in cultivated music, as when the ultimate source of a composition is investigated. Thus music historians may try to trace a musical theme through the various "borrowings" by composer from earlier composer until the real originator of the theme is found. In traditional music the problem becomes substantially greater in cultures which encourage improvisation and where music may be performed with considerable change in each rendition. One must also consider the problems of defining the compositional unit if each rendition or stanza is different, and of dealing with entirely improvised material. These examples show why the history of individual pieces has rarely been studied, especially in non-literate cultures.

Some Methods of Investigating Change
Among the various approaches to historical problems in ethnomusicology and the interpretation of descriptive data in a diachronic manner, two are selected for brief discussion here: evolutionary and geographic. We label an approach evolutionary if it recognizes a generally valid series of stages of musical style, into which the data are then fitted. The schemes arranging musical material into a time sequence may apply to generalized concepts or to more specific local ones. For example, it is believed by some that each culture goes through a stage of monophonic music, after which polyphony is developed. Cultures which have a great deal of polyphony, such as many in Negro Africa, are thus assumed to be higher in the musico-evolutionary process than those which have very little polyphony, such as 'the North American Indian. The difficulty with this view is that the results might be reversed if some other element of music were the criterion. It could be postulated, for example, that there is an evolutionary process from short, repetitious forms to longer, strophic ones; in this case the Indians would be ahead of the African Negroes, assuming that typical rather than exceptional examples are used. In a classification of the music of the Finno-Ugric tribes in Russia, Lach (1929:11) states that the simple forms of the Mordvin, which are usually repetitious, place that tribe in a lower evolutionary category than the Chuvash, who have many strophic songs with four different phrases per song. The Cheremis, who have many forms which begin in a typically strophic manner and then go on to repeat one phrase several times, are placed in an intermediate category. The same data could be interpreted differently, and without the use of evolutionist schemes. One of the problems faced by the classifier of tribes according to evolutionary principles is the selection of representative material. There would be different results if one used the average and most common, or the simplest, or again the most complex material within a repertory as a basis for comparison. Furthermore, the assumption that all cultures ultimately pass through the same set of musical stages is even superficially only valid if one makes the grossest sort of distinctions. Evolutionary schemes must thus be limited, if they are to serve any useful purpose at all, to restricted areas and phenomena, and the existence of other factors must always be admitted.
Universally applicable stages for elements of music other than form have also been postulated. They are usually quite logical and would be accepted as valid for most cases even by opponents of evolutionist approaches. For example, the development of scales from two or three to finally four tones probably took place in many cultures, although a development of tetratonic from ditonic without the intermediate tritonic is also possible. Similarly, most strophic styles probably developed from simple repetitive forms, but this does not necessarily indicate the future development of strophic forms in all styles which now have only simple repetition of single phrases.
There has been special confusion in the case of rhythm. Some students believe that metric chaos, or the absence of metric organization, precedes unification into metric patterns.
On the other hand, it might be assumed that metric simplicity, repetition of a simple metric unit such as 4/4 or 3/4, precedes heterometric structure which, to the listener, may appear confusing and unorganized. A given piece may be analyzed as metrically unorganized or metrically complex, and many evolutionist statements in ethnomusicology have been made on the basis of such subjective distinctions.
Evolutionary stages have also been hypothesized for the development of repertories. Bartók (1931: 12) postulates three stages in the development of folk music. First the repertory is homogeneous; all songs are in the same style. Then special substyles are developed for certain categories of songs, such as Christmas songs, weddings songs, and music for other ceremonies. In the third stage these ceremonies disappear, and with them the correlation between song functions and musical styles. This scheme seems applicable in some cases, if we take the music of some non – literate cultures as examples of the first stage. It is not known whether Bartók also allows for the appearance of intermediate stages caused by the impoverishment of repertories, whether he believes the third stage to be attainable in all cultures, and whether the disappearing ceremonies and the submerging of their peculiar styles are not replaced by other, similar categories.
Other such schemes have been advanced; some have been mentioned in Chapter 1. Characteristically, they divide music history into three stages (is this a commentary on Western cultural values?). Evolutionary schemes perhaps have their greatest value in their contribution to arrangement and classification of musical material. And while they frequently help to explain individual cases of development, they have never become generally acceptable. We can say categorically that there is no evidence to support the notion that music passes through pre-determined and predictable stages.
The geographical approaches to historical questions have been more valuable. They are used because anthropological theory has developed hypotheses to the effect that certain kinds of geographic distribution indicate the likelihood of certain past conditions or events.
For example, the distribution of a cultural trait (an instrument, for example) in noncontiguous, scattered areas may mean that this trait was once widespread and has remained only in isolated pockets. The fact that certain musical features have the same geographic distribution as those of another facet of culture may mean, possibly, that they have been associated for some time. Again, the fact that a trait is found in a highly developed state in one spot on the map, and less well developed in the surrounding area, may mean that it originated in the center. At times too much has been made of the importance of geographic data in ethnomusicology, especially so far as their interpretation along the lines of historical perspective is concerned. But while their importance is probably greater for simply classifying and presenting information, their value to the study of musical prehistory must not be underestimated. We must, then, turn for several pages to a discussion of some of the problems of studying the distribution of music.
Our historical and geographic considerations are then combined in our discussion of musical areas, below.

Studying the Distribution of Music
There are two main uses which ethnomusicologists make of geographic concepts: 1) They plot the distributions of musical phenomena, entire styles, individual compositions, but most frequently of individual traits abstracted from their styles which can be present in various stylistic environments. An example of the latter is a scale type found with various kinds of meter or form, so that its distribution is not affected by the other elements in the same composition. 2) They classify the world in terms of musical areas which exhibit some degree of internal unity and contrast with neighboring areas.
During the late 1950's, several publications have mentioned the desirability of mapping the distribution of music in the world. Paul Collaer (1958) indicates that mapping the distribution of individual traits or features of music would yield historical insight in various ways. Later, Collaer (1960) began publishing such maps in earnest. Fritz Bose (1959) goes so far as to postulate specific steps in making distributional studies and setting their results down on maps. He suggests 1) making individual maps of single elements of music and musical instruments; 2) mapping the use and function of each of these: 3) preparing comparative maps; 4) making maps comparing musical features with other aspects of culture and language. Bose's scheme is obviously predicated on work primarily based on instruments and does not go far toward solving the problems inherent in the preparation of maps for music per se. He is desirous, evidently, of using those aspects of music which correspond most closely in their nature to those elements of culture already treated cartographically, that is, instruments. The problems we will investigate in this section are primarily those, however, which do not have analogous features in other fields of culture frequently described with the help of maps.
Certainly statements of the distribution of music, that is, statements which indicate the geographic location of musical phenomena, have been made in hundreds of publications. In the field of musical instruments, maps have been made by many, especially Sachs (1929), Roberts (1936), and Izikowitz (1935).
Maps of musical styles have been less common, but do appear in some publications – for example those of Collaer (1960) and Jones (1959). However, th over – all problem of the distribution of musical phenomena in the world has not been laid out in theoretical terms.
The purpose of this section is to outline the kinds of things in music which can be studied in terms of their distribution, and to indicate some of the kinds of musical distribution which can be found in the world's cultures.
Studying the geographic distribution of musical phenomena is, generally, a more complex matter than the typical distributional study in anthropology. Anthropological statements of distribution have usually (but not always) restricted themselves to saying that a given trait is present – or absent – in the culture discussed. To ask whether music is present or not in each of the world's cultures would not yield a variety of answers, since cultures without music of some sort (using the broadest definition possible) are unknown.
What we want to know is what kind of music is found in the various parts of the world, and how the world's peoples are related musically. Ethnological studies of distribution, with their breakdown of traits into units which simply are or are not present in a given place, are most easily approximated by musical instrument studies. Thus, we could state that the banjo is found in a certain group of cultures, nations, tribes, or other kinds of units, and not found in the rest of the world.
Taking the places in which the banjo exists, one could map the distribution of the number of strings, the material from which the instrument is made, and so on. Such a study would tell us a good deal about the qualities of the banjo around the world. But a similar sort of study for musical style would be less productive, mainly because music itse1f cannot be broken down into easily circumscribed components. The problem of mapping musical distribution is primarily one of identifying relationships among forms which are not identical or similar, and of rejecting as unrelated others which may seem, on the surface, to be related. For example, one might wish to decide which of various similar tunes are actually variants of one basic type. Or, one could try to find out whether two slightly different pentatonic scales are really sub – types of one form.
There is, moreover, the problem of deciding on geographic units to be used as a basis for stating distributions. Should we use units determined by political affiliation, by language, or by physical geography? (Fortunately, these would often coincide.) Should smaller units, such as villages, be taken into consideration? Or perhaps families, which are often the units of musical distribution which can most conveniently and accurately be studied? And let us not forget that, as in speech, each individual has his own musical peculiarities and should perhaps be considered as the basic unit of musical style. But at that point, the problem becomes academic: world – wide distribution of musical phenomena could only be plotted by reference to a combination of linguistic and political units, if we limit ourselves to the present state of musicological information. On the basis of these units, let us proceed to a presentation, in outline form, of the alternative approaches to distributional studies in music:
1)        Approach by element of music, such as type of scale, kind of rhythm, polyphony, etc.
a)  General. This would include, for example, a statement on the distribution of pentatonic scales in general, or of general (nonspecific) types of pentatonic scales such as the scales without half-tones, or of rhythmic aspects of music such as heterometric structure, or the isorhythmic stanza, or of broad types of polyphony such as imitation.
b)    Especial. Here would come statements of the distribution of specific patterns, or of melodic types such as the well – known terra type of cascading melody used by the Plains Indians. There’s, of course, a large area of overlap among these "general" and "special' elements of music. The special elements would seem to be much harder to handle, being harder to define and to identify.
A set of maps giving the distribution of these elements of music would yield, by itse1f, a sort of picture of the world of music at a given point in time. But it would be, in some ways, misleading because it would ignore relationships which exist at other levels of distribution discussed below.
A refinement of the technique of plotting musical elements by themselves is the quantification of material. This is an approach which has hardly been used as yet – and which, in the present state of knowledge of the world's music, cannot be considered all too reliable. Nevertheless, it deserves mention because of its potential importance.
In saying that the mere presence or absence of music would make no good basis for study because music exists in every culture, we neglected to point out the quantitative aspects of musical culture. Immediately, we would find differences in the amount of music existing in each culture. The number of compositions in a repertory, the amount of time spent in musical activity, the amount of music known to an individual (including the songs or pieces he recognizes, and the number he can perform) could be studied and mapped for comparative purposes. The counting of compositions would itse1f be problematic because of the difficulty, in some cultures, of identifying a compositional unit and distinguishing it from its own variants and unrelated but similar units. Finally, the number of styles or distinguishable bodies of music in a repertory could be counted. In some cultures – especially the simplest ones – there may be only one such style, while other repertories (such as that of the Shawnee) have several distinct styles. High cultures of Europe and the Far East may have many more, depending on the time of origin of each composition, the instruments in their variety, the function of music (a church music style, a dance music style, etc.) and the segment of the population using it (popular vs. "classical" music). A comparative study of the numbers of styles in cultural units would indeed yield interesting results; but first we would have to define "style" in this sense of the word.
Besides counting compositions or styles, quantification of musical data in a technical sense could play a major role in distributional studies of individual elements of music, beyond indicating simple presence or absence. There are few elements of music (such as pentatonic scale, strophic form, etc.) which are not found practically everywhere. When Collaer (1958: 67) indicates the desirability of mapping the distribution of the anhemitonic scale, he must mean some sort of quantitative approach, for some compositions using such a scale are found in practically every culture. Most useful for various sorts of studies utilizing distribution would be an indication of the strength of this scale in each repertory: is it found in every song, or, in the vast majority (as in Cheremis songs), in half of the songs (as in some Plains tribes), or only occasionally (as, perhaps, in nineteenth-century Western cultivated music) ? Of course, such statements would have to be based on large samples of material from each repertory, samples which are really representative, for many cultures are represented in the ethnomusicological literature by large, exhaustive collections from single ceremonies which might still not give accurate pictures of the entire musical cultures.
Since studies of the percentage of compositions in a repertory which contain a given trait are not common, an example of such a study is briefly presented here. It is, unfortunately, based on small samples of varying reliability, and should be viewed as figura a sample of method rather than as a statement of musicological fact. It concerns the phenomenon of North American Indian music known as the "rise» identified and so designated by George Herzog (1928) : In a song with a non-strophic structure, a short section is repeated at least twice, then followed by another bit of music at a slightly higher average pitch, which in turn, is followed by the lower part. This alternation can continue for an unspecified period of time, but the lower section tends to appear more than once at a time, while the higher or "rise" section is sung only once each time it appears.
The rise occurs in the music of a fairly large number of tribes along both coasts of the United States and Canada. Figure 12 gives the distribution among those tribes which have been studied, and the approximate percentage of songs of each tribe in which the rise is found. It is strongest (occurring in over 50 per cent of the songs) among the Yuman tribes of the Southwest, and among the Miwok, Pomo, Maidu, and Patwin of central California. In the repertories of the Northwest Coast Tsimshian and the southeastern Choctaw it occurs in 20 – 30 per cent of the songs; among the northeastern Penobscot and the northwestern Nootka, it occurs in 10 – 20 per cent of the songs; and in the songs of the Kwakiutl of the Northwest Coast and Vancouver Island as well as the southeastern Creek, Yuchi, and Tutelo, in less than 10 per cent. Considering that most of the other tribes of the coasts are musically not well known, it is probable (provided the samples used are reliable) that the rise has a center of distribution in the southwestern United States, and a thinning – out strength across the southern part of the United States and up both coasts. This information can be interpreted in several ways, but at any rate it is more valuable than a simple statement that these tribes have the rise in their repertories.
Some work along similar lines in North American Indian music has been done by Frances Densmore (1929).Her comparative tables usually include the tribe or tribes which the study at hand contains (Pawnee in the case of our reference) and compares them only with figures representing the entire group of tribes whose music she had previously studied. Nevertheless, if her analyses were reliable, it would be possible to make cartographic representations of her figures which would, then, indicate the distribution, in quantitative terms, of certain special and general elements of music in North America.
A. M. Jones (1959, vol. 1) has made a map of types of harmony in Negro Africa, using as a basis the main interval between the voices (unison, thirds, fourths – fifths).No indication is given on the map of the amount of such harmonic music in each repertory, and of overlapping distributions (if any).
Marius Schneider (1957:13 – 14) would evidently be opposed to the approaches outlined in the last three paragraphs, for he believes that certain types of music are inevitably linked to certain types of economy, such as hunting, sheep herding, and farming. If a hunting culture has in its repertory music which is of a style different from the main body of its music, Schneider would presumably consider it non-authentic. It is evident that if we were to make a musical map of the world – based on elements of music or even on the distribution of individual compositions – according to Schneider's view, we would have to distinguish between the music which could be said to belong properly to a culture, and that which has infiltrated it from the outside, and we would have to base our distribution somehow on this distinction, rather than on quantitative considerations. This would throw us again into the knotty question of what is "the real" music of a culture, a question discussed in Chapter 6.
2)    Distribution of compositions. While we could follow certain kinds of scales and rhythms throughout the world and get one kind of picture or map, we might approach the entire problem of musical cartography from the point of view of the individual compositions – pieces or songs. Our first problem would be to find out what the unit of musical creativity actually is; for although in Western cultivated music we might have no difficulty identifying a piece, this is more difficult even in Western folk music. In non-literate cultures we are sometimes bathed by the way in which informants will insist that two musical items which seem identical to use are really independent pieces, and how, in other cases, two seemingly very dissimilar songs will be called alike by the informant.
Assuming that we can come to a decision on what constitutes a composition, we must then identify a) similar forms which are genetically related, and b) similar forms which are similar only because the style (the scale, rhythm, form, etc.) in their repertory makes the independent creation of similar forms likely. We are concerned (as we were in Chapter 6) with distinguishing musical content from musical style. Plotting the distribution of songs and their variants has hardly been attempted. An approach (in which genetic relationship is not necessarily assumed) has been made by Wiora, who gives similar tunes from many parts of Europe in order to show the stylistic homogeneity of European folk music (Wiora 1957:50 – 53). Here it becomes evident that distribution of elements of music may be quite contrary to distribution of compositions, at least within certain limits. The variants of a tune as sung in Hungary, Spain, and Ireland are very different, perhaps because the styles of these three cultures, as determined by the elements of music, are so different. On the other hand, the three styles are relatively alike when compared to African or Chinese music, and perhaps as a result, the composition in question is limited to Europe and does not appear in Africa or China.
Again, Marius Schneider (1957: 24) offers an interesting sidelight, saying that a melodic type (i.e., a group of melodies similar enough so that genetic relationship could be inferred, or a type of music the various forms of which have some inner relationship which cannot always be identified by analysis) is revealed above all in performance and in the peculiar way in which metre and melodic line coalesce in the rhythm. On paper it can be grasped only incompletely, but the ear detects it immediately. The same melodic idea, appearing simultaneously in the music of two different peoples, can be used by each of them in a different type. On the other hand, the same type may appear in two different melodies although the actual notes may have little in common.
Recent work by Alan Lomax also emphasizes the importance of the manner of performance rather than the melodic, rhythmic, and formal aspects of music when it comes to deciding upon the world map of music.
We must, then, distinguish among three kinds of phenomena when considering the distribution of compositions: the variants – definitely established as such – of a piece; similar melodies without definite genetic relationship, such as the «wandering melodies" which are of long standing as musicological curiosities; and melodic types, which are somehow intermediate between pieces and specialized elements of music, such as the “rise”.
The distribution of compositions in non-literate cultures has not been studied thoroughly.. Rhodes (1958) has published a rare exception, a study of the distribution of one Peyote song.
But detailed investigations of this kind would presumably show whether songs coincide in their distributions and form “areas”, or whether each song has an area of its own which is different from the distribution of every other song. Quantification of such data would involve the number of variants of a song found in each culture or sub – culture, the number of individuals knowing the song, and the amount of use to which the song is put.
3) The distribution of musical styles, or the identification of musical areas in the world, has been attempted by various scholars. A musical area is one which exhibits a degree of homogeneity in its music but is larger than the tribe, village, or language group. As such it is similar to the culture area used by American anthropologists (for definition of which see Kroeber 1947:3 – 7). The concept of the musical area is beset by some of the same problems faced by users of the culture area concept; among them are the difficulty of formulatingBruno Nettl - Theory and Method in Ethnomusicology criteria for identifying the area, and the lack of measuring devices for degrees of musical similarity or stylistic unity. Like the culture area, the musical area is primarily a tool for musical classification, and further conclusions about it as a unit of historical development may be drawn only with great caution. Ethnomusicologists began constructing musical areas in order to systematize the vast amount of stylistic data which is available about the hundreds of tribes and ethnic groups in each continent. The fact that these areas may be functional in other ways was not foreseen at first and still does not ordinarily play a part in their construction. 

Musical Areas in Ethnomusicological Literature
Although sometimes approached consciously and systematically, musical areas have also appeared in ways only incidental to the research which produced them. It has usually been assumed that musical distributions would coincide with other anthropologically defined areas. Thus, E. M. von Hornbostel believed that some racial areas, for biological reasons, were also musical units. He assumed, for example, that the American Indians shared a single main style, now known to be common only to some of the tribes in North and South America, and that the manner of performance, especially the voice timbre, was the main criterion of identification (HombosteI1923). Accordingly, he at times stated that the performance practices in singing were determined racially, but the other aspects of the style were learned (or determined culturally).This theory was also supported by Bose's experiments (Bose 1952).The notion of racially determined musical areas is otherwise widespread and can be accounted for by the tendency of a racial group to be located in one area of the world, and incidentally to constitute a cultural unit of some sort. This tendency was exploited by myself in an attempt to divide the world into three large areas (Nettl 1956: 142 – 43).The Americas and the Far East make up one of these areas, and it could be called the Mongoloid area, although it is evident that the cultural influences of Asia on America may be responsible for the similarities between Far Eastern and American Indian music, rather than any biologically inherited style preference. In other words, although racially defined areas may coincide with musical areas, the notion that biological inheritance is the cause need by no means be accepted as the explanation.
The areas defined by culture in general have in several investigations been assumed to be related to musical areas. Using the culture area concept, Helen Roberts' (1936) description of North American Indian music, one of the classical attempts to construct musical areas, was really a description of musical style in each culture area. Nevertheless, Roberts also subdivides some culture areas, such as the southwestern United States, where she identifies a Hokan, a Shoshonean, and a Navaho style – although these subdivisions are not found in the divisions of the continent into culture areas which are generally accepted. Similarly, cultural units are the basis of musical distribution in Merriam's division of Negro Africa into the Guinea Coast, the Congo, and the Eastern areas (Merriam 1953; 1958).The use of both style traits and instrument distributions for constructing areas is a feature of Merriam's study (while Roberts constructs separate instrument areas), and it is important to note here that instruments often serve as important criteria for culture areas themselves.
But since the presence of an instrument does not really give information about the style of the music performed on it, instrument distributions do not have an essential place in this discussion. Needless to say, however, a culture whose musical repertory is dominated by instruments, such as Negro Africa, may have its styles determined to a large degree by these instruments and the kind of music they are capable of producing. In other areas, however, the distribution of a particular instrument may have no relationship at all to the distribution of vocal styles. This is true, for example, in the case of panpipes, which are found in spots throughout the world in combination with many different vocal styles; the similarity of panpipes in Oceania and South America does not have a close parallel in vocal music.
Quite different from the use of areas in a classificatory sense (in both music and culture) is the Kulturkreis, a concept devised for culture at large which cannot easily be transferred to a single aspect of culture such as music. The theoretical differences between a Kulturkreis and a culture area include the following characteristics of the former: 1) it need not be contiguous on the map, 2) it is usually based on a few key traits, and 3) it may overlap with others since it is not only an area but also a historic era (see Lowie 1937: 177 – 94).The difficulty of transferring such a concept to music alone is obvious. But it has nevertheless been done by a number of scholars, particularly with reference to musical instruments (for example, in Sachs 1929), but also with musical style as a whole (for example, in Danckert 1939), and with individual elements of music. Schneider (1934), although he does not label his attempt as relevant to Kulturkrei’s theory, is clearly under its Influence in establishing areas for polyphony (south Asia and South America; Micronesia; Polynesia; Africa).In uniting south Asia with South America, for example, he postulates a noncontiguous area and, characteristically for the Kulturkrei’s school, he gives these areas the significance of historic units – they indicate a particular stage and time of development – even though he does not pretend that other traits will have the same distribution.

Identification of Musical Areas
Assuming that musical areas exist as functional units, their very identification poses methodological problems, and a number of alternative methods are possible and may produce differing results. The student has the choice, for example, of using clusters of traits, single important traits or what we may call "specialized" or particularly distinctive traits as the main criteria, or he may make a strictly inclusive, statistical statement which treats equally all described traits of a given style or corpus of music. The basis for constructing a musical area is usually a group of descriptions of tribal and regional styles which must then be either lumped or separated. Statistical differences among such styles can easily be found, as can be seen In a study by Merriam (1956) ; but statistics of this sort can also be misleading if not properly used, for they do not separate significant from insignificant distinctions.
Using North America as an example, we find that musical areas would differ depending on the criteria used, but the different constructions would tend to have something in common.
This is perhaps evidence for the hypothesis – discussed below – that musical areas are actually functioning units in culture. If single traits or elements of music are used as criteria, large areas tend to emerge. For example, if melodic contour is the only criterion, two areas could be identified, one occupying the central portion of the continent, with heavily descending melodies, and one occupying the coasts and the northern and southern extremes, with undulating contours. But in each area the diversity would otherwise still be great.
The use of specialized musical traits, that is, of traits which have been developed to some degree of complexity and intricacy, and which are, on the whole, restricted to single regions, is another possible approach. Of course it is necessary to distinguish between the greater or smaller degree of presence of a trait and between the simple presence of a trait in one repertory compared with its complete absence in another. In the latter circumstance we would have an example of a specialized trait; but there are few musical traits which are completely absent in any culture. Applying this criterion to North America, the isorhythmic structure coupled with descending, cascading melodies would make possible the identification of a musical area around Lake Superior, an area quite small compared to the culture areas.
Again, the use of only two rhythmic values in the songs of the Apache and Navaho would make these tribes the sole inhabitants of a musical area, even though they do share other musical traits with some of their neighbors.
A cluster of musical traits seems t9 be the most common and successful criterion of a musical area, especially if some of these traits are "specialized" while others are shared with some, but not all, neighbors. This method is illustrated in the diagram in Figure 13, in which trait clusters and a specialized trait are found in a hypothetical continent. The fact that areas 1 and 2 share traits A and C, while areas 2 and 3 share traits B and D, makes area 2 the only one with all four traits, and this information could be sufficient to call the three areas genuine musical areas. But it would be possible also to interpret this entire “continent" as a single musical area, with area 2 a kind of center of development or distributional nucleus. Since area 2 also possesses a specialized trait, E, however, which its neighbors lack, this interpretation seems less useful than our first one.

Figure 13. Diagram of distribution of traits in musical areas.
This method of combining trait clusters with specialized traits was used by myself in the identification of North American Indian musical areas. The division of Negro Africa by Merriam r(1953) is similar, for it postulates three areas, the center one of ; which shares with both neighboring areas certain traits and develops some of them to a specialized degree. The implied construction of a musical area by Picken (1937) in Southeast Asia, on the other hand, illustrates the use of a single, specialized trait as a criterion.
The identification of borders and their nature is a problem which logically follows these considerations. For while the borders of a musical area are at times clear – cut, they may also be so vague in other cases that the areas are clearly marked only by their centers. Thus the Plains area of North America is characterized at its center (Arapaho and Dakota tribes) by sharply cascading, terrace – shaped melody, large range, great vocal tension, scales of four or five tones, large intervals, and melodic fourths at key points. At the eastern boundary of the Plains, the so-called "wild rice" (Menomini and Winnebago) and Prairie (Pawnee) districts, the cascading melodies are smaller in number and are replaced by a more generalized contour which happens to be similar to that of the Eastern tribes, and the tetratonic scales subside in favor of five – and six – tone ones (as in the eastern United States).On the other hand, the eastern characteristic of responsorial singing does not extend to the Prairie and "wild rice" tribes, which makes these something of a no – man's land between the Plains and the East. On the western border of the Plains, the Plains traits do not, however, extend to the neighboring Great Basin area (or did not, until recently) – or vice versa – except among the Ute Indians. This can perhaps be due to the natural barrier of the Rocky Mountains. The difficulty of identifying musical areas and their boundaries is even greater in the Old World, where influences between high and non-literate cultures and the more rapid cultural changes have produced combinations of styles whose distribution has changed more rapidly in recent centuries than has the more stable North American Indian music.


Musical Areas and other Distributions
The fact that musical styles influence each other is obvious, and that style combinations should emerge at musical area boundaries is inevitable. What is perhaps surprising is the fact that the borders can be identified at all, and that some are relatively sharp. There are at least two possible reasons for this situation: 1) the musical areas coincide with other areas, natural, cultural, and linguistic; and 2) the style elements in a musical area complement each other to such an extent that for structural reasons they coincide in their distribution. But in separating a style or repertory into its components, we must be careful to distinguish between the elements of a style (rhythm, melody, form, etc.) and the song types (based on functions of the songs).
Natural areas evidently coincide with musical areas in some cases, and natural barriers may also be effective musical barriers.
Very obvious is the Himalaya chain, which draws a rather sharp line between two main types of oriental music. Islands and island groups may be musical areas, although water is at times an ineffective barrier. Micronesia and Melanesia could be construed as musical areas (based on small intervals and parallel polyphony in the former case, and the development of more complex forms of polyphony in the latter), but Indonesia seems to have been subject to more influence from several Asian styles than these mainland styles have been influenced by each other. In the style of its folk music, Great Britain seems to be aloof from the neighboring European countries whose musics are, by comparison, more strongly interrelated.
Areas determined by vegetation and fauna seem to be the bases of musical areas in Africa, for here the boundaries coincide approximately with those limiting cattle breeding. In North America, the island – and shore – dwelling Eskimo and Northwest Coast tribes belong together musically, as do the inhabitants of the Great Basin desert area. The possibility that a natural environment itself determines a musical style must not be rejected outright, although it cannot carry great weight. The development of instruments and of functions of music is no doubt affected by such conditions. Finally, however, some musical areas do not coincide with gross natural areas at all, and where they do, direct influence of the natural environment on musical creativity can hardly be assumed.
The possibility of racial distribution coinciding with musical areas has already been mentioned, and the direct influence of racial (physical) factors in music seems unlikely or at least unproved except in a cultural context. The relationship of cultural area to musical area is generally close, even though the two rarely coincide exactly. Thus, in North America, the tribes of the eastern United States form a cultural and musical unit; the Plains tribes, although they are linked to the Pueblos in musical character, constitute an area in both respects, as do the Northwest
Coast tribes and those of the Great Basin area. The cultural contrast between East and West Africa is reflected in music as is that between Negro and North Africa. Europe is, on the whole, a cultural unit as well as a musical one, in both folk and cultivated music.
The points at which cultural and musical. areas do not coincide are also of interest. In the southwestern United States, for example, a single Indian culture area contains tribes belonging to three musical areas (Pueblo, Yuman, Navaho – Apache), perhaps indicating that in this case the musical traits of an earlier period remained at least partially intact while the other aspects of culture changed more rapidly and amalgamated into a more unified pattern.
In Europe, the cultural entity formed by German-speaking peoples does not find reflection in the relatively great differences between north German and Alpine folk music.
The great cultural differences between Japan and China are contradicted by a relative similarity of musical style (but again: how can we measure degrees of similarity?), which may also be a relic of earlier times. Even in these cases, however, the relationship between musical and cultural distributions seems complicated only by what may be a tendency of music to change (in the cases mentioned) at rates different from other cultural elements. The hypothesis that certain culture types (determined by way of reckoning descent, subsistence, etc.) coincide with or determine certain types of musical style need not be accepted, for the actual connection, in human life, between music and other activities, ceremonies, dance, etc., is sufficient to explain the congruent distribution of music and such activities.
The quasi – linguistic nature of music points to the possibility of musical areas which coincide with areas occupied by speakers of a language, or a language family, or other linguistically determined groups. Here also there is conflicting evidence. In North America there is little correlation between language and music; indeed, one of the most closely knit musical areas, the Plains, is divided among five language families (Algonquian, Siouxan, Kiowa, Uto-Aztecan, and Athabascan), while only one musical area, the Athabascan, comprising Apache and Navaho, coincides approximately with a language family. The Indo – European language family does not share one musical style, although a large portion of its speakers, located in Europe, share a broad sort of homogeneity. Several of the Finno-Ugric peoples, along with some Turkic – speaking ones, share some musical traits, such as melodic sequences at the fifth, even though their areas of habitation are not contiguous. The music of the Semitic – speaking peoples can be described as possessing a single style, but it is shared with some neighbors speaking unrelated languages, including Persians, Turks, and to some extent, Spaniards. These examples show that there is only occasional congruency among musical and linguistic areas. In the case of individual languages, the correspondence is much closer, for the obvious reason of simple communication within a language area. But the theory that the origin of musical styles can be traced through language relationships cannot be generally accepted, for musical styles seem to cross language barriers and to be more prone to change and annihilation than basic language relationships.
As we implied earlier, musical areas may tell us something about the prehistory of music, especially if we compare them to culture and language areas. A musical area with a sharp boundary coinciding with a culture area with a sharp boundary may be one which has a long history of stability. Another one which does not coincide with language or culture units may be a layer of material recently introduced – or an exceedingly archaic stratum. An area with much stylistic variety may be one which has undergone frequent contact with other cultures, and constant change. One with a unified style may have existed in relative isolation.
Of course we do not know precisely what historical conclusions we can draw in each case, but there is no doubt that these musical areas can eventually be used to gather important information about the world's musical past, and about the relationship of musical events to events in the history of language and culture.

Musical Areas as Independent Units
It is evident that musical areas are sometimes closely related to natural, cultural, and linguistic areas, but we have seen that they are sometimes quite independent of them, and that they sometimes retain their individuality through periods of stylistic change. One important reason for this kind of cohesion, and one which has perhaps not been sufficiently explored, is the functionality of the individual elements in the total style. Some musical styles are made up of musical elements (rhythm, melody, etc.) which complement each other or which are interdependent to such an extent that a change in one stimulates changes in particular directions in other elements. Thus, a change from isorhythmic to freely moving rhythm may be accompanied by a change from heterometric to isometric structure, a tendency which can be observed in African and New World Negro music.
These complementary changes may be based on the need, in orally transmitted music, for the presence of certain unifying elements as mnemonic aids, and on a desire for a certain degree of unity – bringing simplicity. They are also evident in some cultivated traditions, such as European organum, whose increased complexity seems to have been accompanied by a gradual simplification of meter.
Some musical areas have perhaps achieved stylistic integration, as indicated by interdependence of musical elements, to a greater degree than others, and it is those that have which are probably genuine musical areas. On a large scale, African Negro music, although considerably influenced by outside styles, is a unit whose identity is rather clear. In North America, the Plains and the neighboring Great Basin are stylistically integrated units to a greater extent than, for instance, the Navaho – Apache area, which is not clearly distinguished from its neighbors and whose songs exhibit more variety in style. The number of sub – styles in an area is also a criterion of the degree of integrity in a musical area. An area with a single style or a few overriding traits seems destined to remain intact longer than one with great variety.
A heterogeneous area would appear to be particularly receptive to outside influences, and perhaps it could be interpreted as one whose musical traits have not complemented each other in a satisfactory way, and whose inhabitants are, as it were, searching for the proper degree of specialization in musical style. Accepting these factors, we could consider the possibility of musical areas gradually being formed by the tendency of musical elements to combine in complementary fashion until the proper style has been found, and being, in turn or simultaneously, dissolved by the disrupting influence of outside cultures. At a given time, the world's musical areas may be at various stages of this development: the North American Plains in the perfected stage of integration, but being influenced and diversified in the late nineteenth century by the Ghost Dance and Peyote styles as well as by European music. The area of European cultivated music, on the other hand, may be consolidating itself into a stylistic unit (comparable perhaps to its state during the Baroque period) after a multitude of influences and innovations during the past century – some from the outside, from folk and oriental music – have borne upon it. Needless to say, these statements are highly speculative, but they may help to solve some of the problems connected with geographic distributions in music, and with the phenomenon of musical areas in particular.

Conclusions
Quite aside from the musical area approach, it would also be useful to plot the distribution of stylistic types – such as the North American Indian Peyote songs and the Ghost Dance style, which were superimposed on older tribal repertories, the peculiar style of singing epics in the Balkans, etc. There are some cultures which have several diHerent styles each of which is accommodated more or less equally with the rest, and this is in itself worthy of cartographic and historical investigation. The fact that a kind of combination of musical elements can develop considerable homogeneity and then spread, as a unit, from culture to culture, without necessarily bringing it the individual compositions, is somewhat analogous to the picture of compositions spreading across stylistic lines. In other words, a composition can move – and change its style – to an area with a different style; and a style can move – assuming that new compositions are created with it as a basis – across the lines of distribution of individual compositions.
We have combined the discussion of change and of geographic distribution because these are the broad, comparative, and potentially world – wide ways in which music can be studied as a phenomenon of culture, and iIi which the theories of anthropology as a comparative science can be applied to music. The possibilities of distributional and historical studies mentioned here indicate that the music of the world is indeed a complex phenomenon, inexplicable in terms of any single theory or dogma. The beginnings of musical cartography could proceed along any one of the lines mentioned, but it would hardly be complete if all of the components of musical distribution discussed here were not included.
And the study of the world's musical cultures would hardly be complete without detailed consideration of the manner in which music changes, and the way in which musical phenomena come about.
It remains for us to make some suggestions for independent study on the part of the student. Broad theoretical study in the field of change in music is not well suited to short – term work, nor, as we have seen, is it as &ee of the unproved assumptions and the theoretical biases as one would hope to have it in projects for the beginning student. The most promising approach is perhaps the study of distribution of musical compositions and of stylistic features. Thorough study of certain features whose distribution has already been stated impressionistically, especially for European folk, African, and North American Indian music, should be pursued. The areas mentioned are best because their music has been published in greatest quantity. Types of scales and rhythms as well as form patterns should be used. In all cases, he student should be careful to go beyond statements of the ere presence or absence of a trait, to weigh his findings carefully against the reliability and size of the sample which is used, and to take into account the cultural and linguistic context of the music.
Other projects which need to be pursued involve the study f musical change as it occurs. Finding informants who have made recordings in the past and asking them to re – record is one approach. Observing the change in the repertory of a community r an ethnic organization over a period of months might be useful, and studying the differences in repertory and style between older and younger individuals of a community could be of great interest. Adding concrete data to an area of ethnomusicology which has so far been dependent mainly on unproved or unprovable speculation would appear to be a tremendous service.
