In 2014 Kris Shaffer, Bryn Hughes, and Brian Moseley decided that what the world needed was a real way of teaching music theory in an “inverted,” inquiry-based setting. The requirements were simple.
It should be supplementary to actual music-making, not simply a multimedia version of a traditional textbook where the textbook is the center of the class.
It should be multi-authored, physically hackable, and legally alterable.
It should be accessible from anywhere with an internet connection.
It should be free.
After a successful crowdfunding campaign on Indiegogo, the Open Music Theory online textbook was born.
If you’ve ever wanted to learn music theory, or contribute to how others learn music theory, this is for you. Its open source material can be edited, annotated, rearranged, and supplemented at will, thus making it much more responsive, customizable to your own needs.
