I've been working out some pieces, this time actually mapping them out, rehearsing, the whole bit, before recording them. This gets around the problem of playing-and-forgetting, which I used to have happen all the time, although a basic recording isn't a bad aid to memory. It's an interesting process, and while I'm butting my head agains some other limitations, I'm playing better than I have in ages. (Part of the problem is my technique evaporating when I'm working on those long sustained-tone pieces.)
