Book excerpt: Everyone, according to W.A. Mathieu, is musical by nature—it goes right along with being human. And if you don't believe it, this book will convince you. In a series of interrelated short essays, Mathieu takes the reader on a journey through ordinary experiences to open our ears to the rich variety of music that surrounds us but that we are trained to ignore; such as the variety of pitches produced by different objects, like glassware, furniture, drums—anything you can tap; or sounds that hover on the border of music, like laughter, the clinking of glasses in a toast, or the unintentional falsetto produced by yawning. Along the way the author teaches aspects of music theory that nonmusicians might ordinarily shy away from. He reveals the way of music to be a profoundly spiritual path—one that is everyone's birthright.
