Hello! We are Kate & Ray Harmony AKA Revolution Harmony, a couple of music teachers who make progressive popular music. We also teach open-minded people how to write great songs, using our critically-acclaimed Hack Music Theory books and videos. In between all that, we also run a production studio here in Victoria BC, Canada. We love music, and we don't love spare time!
