This is a really cool book. Danial Levitin, a neuroscientist at McGill University, writes about the cognitive process of listening to music. Layperson and expert-friendly, Levitin defines terms for those who are not familiar with them, but also goes into pretty elaborate detail in his explanation of why we create music, and what goes on in our heads when we listen to and enjoy it. http://search.barnesandnoble.com/This-Is-Your-Brain-on-Music/Daniel-J-Levitin/e/9780452288522/?itm=1&USRI=this+is+your+brain+on+music
