Sing the first two notes of "Somewhere Over the Rainbow" and you have just doubled a frequency. Hum the "Amen" at the end of a hymn and you have played a cadence that composers have leaned on for centuries. Most people already know a great deal of music theory in their bodies. What they lack is the words for it, and words change what you can hear.

This is music theory without sheet music. You will learn why a single plucked string hides a chord inside it, why some intervals itch and others settle, how a waltz differs from "Take Five," why the blues reshaped popular music, and how Ravel built a famous piece out of one melody and a changing orchestra. Afterward, the next song you hear will come apart into layers you can follow: the beat, the chords, the shape of the tune and the plan holding it all together.
