In a clear, accessible, and engaging voice, Powell fascinates the reader with his delightful descriptions of the science and psychology lurking beneath the surface of music. With lively discussions of the secrets behind harmony, timbre, keys, chords, loudness, musical composition, and more, HOW MUSIC WORKS will be treasured by music lovers everywhere. The book also includes a CD of examples and exercises from the book.
