This chapter discusses the relationship of music to colonization and globalization. In the colonies music contributed to the legitimizing of hegemony, while at home it functioned as a means of representing foreign cultures, generally portraying them as both different and inferior. This illustrates how music can serve the ends of cultural and political ideologies, but it can equally be a means to neutralize, resist, or interrogate power. It can also be an instrument of modernization and nation building, as illustrated by the example of China. The chapter then considers examples of cross-cultural interaction and hybridization, ranging from classical and modernist music to the development and globalization of popular musics; it outlines a number of alternative conceptions of ‘world music’ that range from the commercial to the speculative. A concluding section returns to the Prudential commercial with which the book opened, assessing the value of music in contemporary society.
