I honestly think I’m going to have to swear off of [4 3] and playing 3 permanently. It’s just not working, at least not now and possibly not ever. It’s the only time I’ve had to make a movement with my hand at an instrument and had such a powerful conviction that this will simply not be possible.
As a result, I’ve gone back to my old thumb-first bracketing. It will be slower than 180bpm sixteenth notes, but so be it. It seems that my choices are either:
- Play the broken brackets, which will make me slower,
- Force myself to play the correct brackets, which will make me wake up at 2am with throbbing hands no matter how much I “relax,” or
- Allow myself to break the brackets below about middle F and whenever the gap between 4 and 3 is larger than a third, which is just too damned confusing.
From now on, brackets are broken when I’m expected to place [4 3] and play 3, period. Uninjured hands and consistency matters more than following rules that change depending on where my hand is and which will hurt me, I think. I guess we’ll see how it goes.
For now, I place [3 2] at the same time when possible and [4 1] at the same time when possible, especially  — and balance/position my hand around [3 2].
