What makes other sounds different from music???

Indefinite border areas exist, however, between music and other sound phenomena such as speech, and the cultures of the world differ in their opinion of the musicality of various sounds. Thus, simple tribal chants, a half-spoken style of singing, or a composition created by a computer program may or may not be accepted as music by members of a given society or sub-group. Muslims, for example, do not consider the chanting of the Koran to be a kind of music, although the structure of the chant is similar to that of secular singing. The social context of sounds may determine whether or not they are regarded as music. Industrial noises, for instance, are not usually regarded as music except when presented as part of a composition controlled by a creative individual. In the last 50 years, however, new aesthetic approaches in Western music have challenged this view. Composers such as John Cage have produced works in which the listener is invited to hear music in the ambient sounds of the environment.
