This is a plug for Tom Lippincott’s site and its articles. The essay entitled “The Big Three Progressions” is very interesting. I read it a few times before it started making sense, though.
He also has a breakdown of the Coltrane Matrix under “Giant Steps”, which is very helpful. Also, listen to Tom’s playing on Green Dolphin Street in the demos section. AMAZING fingerstyle chops! Check it out!
