Open Music Theory is an open-source, interactive textbook for college-level music theory courses. It supports active music making with concise explanations, reference material, score examples, audio, video, and interactive notation exercises.

The book was created from resources authored by Kris Shaffer, Bryn Hughes, and Brian Moseley, and edited by Kris Shaffer and Robin Wharton. Major funding and technical support for its interactive notation modules came from Trinket.
