Open Music Theory is an open-source, interactive, online "text"book for college-level music theory courses. OMT was built on resources authored by Kris Shaffer, Bryn Hughes, and Brian Moseley. It is edited by Kris Shaffer and Robin Wharton, and is published by Hybrid Pedagogy Publishing.

Major funding and technological support (including the building of the technology behind the interactive music notation modules found in this text) came from the team at Trinket.

The first major edition of OMT was made possible financially by a crowdfunding campaign in the summer of 2014. Many thanks to the donors who supported the project (listed on the about page).

Note: This is a re-skin of the original textbook, revisions to this version are purely vanity. You can check out the original textbook here openmusictheory.com.
