That is very helpful. Agreed, I do need to back track and master some material. I found the Chord Change Drills by Lisa and already started with some of those. But I will be sure to backtrack where I think would be a good spot in the Fundamentals to "land again". At least I have dipped my toes in enough water to know that I definitely want to stick with this and get better.
