Damn brain

The human brain forgets things too quickly, it's very annoying. In particular I'm talking about the precise muscle control needed to play music. I think I've reached a point in my viola playing where I really have to practice quite a lot to get any better. It bites! I work on a piece, get it kind of all right, then start on something else, and after a week of not playing something its gone dodgy again. Unless its fairly easy, like a jig or something, but even those get a bit funky if I havn't practiced them for a while. I don't have that much time to practice a lot either, so it feels like I'm not progressing, though I probably am, slowly. Also my instrument keeps going out of tune, which causes pain to ones ears. This does not inspire one to continue practice.
I should really be playing with a group of some sort, I think it helps a lot (plus it's nice to hear music played by a full orchestra), but I don't know who to play with or when. The two decent orchestras I know of -the Peninsula Symphony and Monash Phil- both practice on thursday night, which is when I have wushu, and i'm doing the wushu dammit!
I'm not giving it up, that for sure. Gotta keep playing music so that when I'm an old man I can sit about the mansion and serenade myself. For this reason I'm making a push to get better at the piano -even though I have no teacher currently-, its such a nice instrument to play to yourself, on it's own I mean.
It's too bad I don't seem to find the time to write much music these days, that was kind of cool.
