Played all sorts of different things, about 40 minutes again. Even harmonics! Started with Lariviere exercises. Those may be a good thing to keep up. Also start PT green band exercises.

We'll see tomorrow if I've over done it.

Played about 40 minutes. Played quietly as I have no remaining callouses whatsoever. No twinges of the thumb joints except when tuning and trying harmonics in left hand. It's basically the same motion so makes sense. My rt large thumb joint inverts when I try to play trills (creating a structurally unsound linkage), which may be why I was never any good at them. Wondering if PT strengthening exercises will help with that.
