It is rare that one finds a book where on opening any page, one is drawn to read on and . . . to read back. Every page has a story, every page a fascinating connection between the universal joy we find in music and some biological or mathematical fact. Here is the place to find out about the way crickets make music, and the McGurk effect! The science comes along gently, never intimidating. Only a neurobiologist who is a master composer and musician could have written this wonderful book!–Roald Hoffmann, author and recipient of the Nobel Prize in Chemistry
