Mark, I would add to your suggestions a most important one-- fretboard geography. Katie spent a lot of time talking about GY and GX, etc chord shapes in my camp. I was totally in the dark about the subject until then. I’ve spent the last few months working through the videos with Allen Munde, and practicing them. It’s hard to learn them on the fly at camp (IMHO).
Try to play through the jamtracks for each song and get a grip on the chords. But I ain’t grading nobody! Just get to Nashville and I’ll make sure you learn and have a blast!
