In a world full of discord and disharmony, everyone agrees that music basically rocks. But few of us know the why, the how or the what of music: why certain songs sound inherently sad, how singers and musicians find a harmony or improvise in a jam session, or the mathematical patterns that determine everything from the spacing of piano keys to the thickness of guitar strings. Thinking Musically is the book that shows you how music "works," without tying you up in formal musical training. Using clear, everyday language and simple analogies, this book will give you the magic of music.
