World music refers to all music that is not part of the modern Western music and originates outside the cultural influences of the English-speaking countries.
The appeal of Western civilization to the exotic traditions of folk music can be traced confidently from Baroque music. There are many genres at the junction of ethnic and classical music.
In the 1960s, many rock musicians resorted to world music. For example, The Beatles blended some Indian elements into their music.
The genre is continuously evolving and expanding its influence into not only classical sounds but such popular styles as reggae, alternative rock, etc.
