I played through Kummer #8, which is not as super challenging. I also played through the groups of 4 eighth notes from both #8 and #4. I’m also planning to learn some music theory. I’ve already had my full practice for today, but in between chores I come back and play for a few minutes.

I was planning to get the Berklee series (this links to amazon.com). I thought this would work well because the school has a good rep, and the lessons seem at the right pace.
