I'm wondering if there's a cheat sheet of chords on all positions up the neck somewhere. I saw someone playing an F chord somewhere in the middle of the neck, and it got me thinking. It sure would be nice to play the same chord someone else is playing, but somewhere completely different, and be able to go right to it, without figuring out how to build it on the fly. I got a chance to sit in with my brother's band lately, and I hate having to stick with the bottom half of the neck, mostly playing open chords to join along. Mostly just blues songs, so 7th and 9th chords would be preferred. Major and minor also. Has Griff covered this, and I've either missed it, or haven't gotten to it yet? Thanks!
