Thanks for sharing - I really like his style.
Here's a general question, which I hope doesn't derail the thread too much.
At the end of the clip he talks about the circle of fifths. Since the first time I had this explained to me (about 25 years ago, by a music teacher friend, who thought it would change my life), I've literally failed to see what practical purpose I'd use it for. I'm clearly missing something - can someone put me out of my misery?
