I am a retired math teacher and have always been good at assessing strengths and weaknesses when it comes to designing curriculum for studying anything. Except it turns out for myself. I like the fact that this is an acoustic challenge, because I have a tendency to avoid acoustic because it harder to execute and make sound good. You can’t hide your bad technique. I also like that you started with the diatonic scale, so what you’re playing sounds musical in the very beginning. I was reticent to join in, but it is perfect for me, even though I’ve been doodling for 30 plus years. I like what you have chosen to start with and I enjoy persisting and making progress through things I usually avoid. Thanks, Brian.
