Oh, thanks. I realized today that I forgot to explain the last shape that I played in the introduction. Maybe that should be the extra credit part for folks?

I think it's one of the neatest things on the guitar: how the G shape and the A shape connect and give us so many options for added cool tones. Maybe someone could shoot a response video for it if they were interested.
I also plan on doing one soon (tomorrow?) that shows how to use the dominant 7 forms from the CAGED system to create a blues chord/melody solo. Thanks for the kind words and encouragement, this is a real blast!
