I found my areas that are a struggle, and I focus on that right now. Mostly, the passive harmonic slurs around 4th space D and higher are a struggle. Most all articulation stuff (passive) is a breeze right now. Also, I’m doing lots of the early Ruby stuff since that’s what seems to help work on my bottom lip from rolling in.
I’m also interested to see if any full time players are starting completely over, as a beginner would, with a whole new set point after the ahah-ooohs.
