The term "world music" encompasses both folk and popular music across the globe, as well as the sounds of cultural encounter and diversity, sacred voices raised in worship, local sounds, and universal values. It emerged as an invention of the West from encounters with other cultures, and holds the power to evoke the exotic and give voice to the voiceless. Today, in both sound and material it has a greater presence in human societies than ever before.

In this new edition of his Very Short Introduction, Philip Bohlman considers questions of meaning and technology in world music, and responds to the dramatically changing political world in which people produce and listen to world music. He also addresses the different ways in which world music is created, disseminated, and consumed, as the full reach of the internet and technologies that store and spread music through the exchange of data files spark a revolution in the production and availability of world music. Finally, Bohlman revises the way we think of the musician, as an increasingly mobile individual, sometimes because physical borders have fallen away, at other times because they are closing.
