I enjoyed Musicophilia by Sacks tends to write about the unusual. A good book which deals with the ways in which we all perceive and enjoy music is "This is Your Brain on Music", by Daniel Levitin, a musicia, record producer and now a neuroscientist. It's very readable and explains how our brains work when listening to music, starting from explanations of what is meant by musical terms which we all use, but may mean different thing to different people. Well worth reading. O.C.V.
