Composer Alan Belkin is offering another free class via his Youtube chanel. This time he's teaching counterpoint. It's funded via patreon and his own funds. He's a talented composer with an impressive career as a composer and educator. Like most theory courses, it's not aimed specifically at guitarists but should still prove to be very useful for those interested in counterpoint and composition.
Here's the first video in the series. He has three so far. The others can be found on his Youtube chanel in his counterpoint playlist.
