Ethnomusicology

In the West, much of the history of music that is taught deals with the Western civilization's art music, known as classical music. The history of music in non-Western cultures (" world music " or the field of "ethnomusicology") is also taught in Western universities. This includes the documented classical traditions of Asian countries outside the influence of Western Europe, as well as the folk or indigenous music of various other cultures. Popular or folk styles of music in non-Western countries varied from culture to culture, and period to period. Different cultures emphasised different instruments, techniques, singing styles and uses for music. Music has been used for entertainment, ceremonies, rituals, religious purposes and for practical and artistic communication. Non-Western music has also been used for propaganda purposes, as was the case with Chinese opera during the Cultural Revolution.

There is a host of music classifications for non-Western music, many of which are caught up in the argument over the definition of music. Among the largest of these is the division between classical music (or "art" music), and popular music (or commercial music – including non-Western styles of rock, country, and pop music-related styles). Some genres do not fit neatly into one of these "big two" classifications, (such as folk music, world music, or jazz -related music).

As world cultures have come into greater global contact, their indigenous musical styles have often merged with other styles, which produces new styles. For example, the United States bluegrass style contains elements from Anglo - Irish, Scottish, Irish, German and African instrumental and vocal traditions, which were able to fuse in the United States' multi-ethnic " melting pot " society. Some types of world music contain a mixture of non-Western indigenous styles with Western pop music elements. Genres of music are determined as much by tradition and presentation as by the actual music. Some works, like George Gershwin 's Rhapsody in Blue, are claimed by both jazz and classical music, while Gershwin's Porgy and Bess and Leonard Bernstein 's West Side Story are claimed by both opera and the Broadway musical tradition. Many music festivals for non-Western music, include bands and singers from a particular musical genre, such as world music.

Indian music, for example, is one of the oldest and longest living types of music, and is still widely heard and performed in South Asia, as well as internationally (especially since the 1960s). Indian music has mainly three forms of classical music, Hindustani, Carnatic, and Dhrupad styles. It has also a large repertoire of styles, which involve only percussion music such as the talavadya performances famous in South India.
