 As observed by Young (forthcoming: chapter 2), it is appropriate to include medieval Islamic philosophy in a survey of Western musical thinking, as Islamic philosophers relied largely on the same Greek authors that were central to the European tradition. In fact, translations of Greek works were more widely available in the Islamic world. Partly because of their earlier contact with Aristotle’s philosophy, Islamic philosophers are more inclined to value the sensory character of music and to accept it as an object of aesthetic appreciation.
