I did two years of fiddle lessons in my 20s and played just for fun at home until three years ago. It's very meditative and seems to create some connections in the brain that are useful for other things as well, anyone else here find that playing an instrument or singing does that? I had to put my fiddle on hold, and a fair bit of other stuff, when we started building our house, because that takes up a lot of time and energy. I'll definitely get it back out when we finish. The acoustics here are going to be super! (High-ceiling straw bale house.)
Also used to sing in a choir; loved madrigals, folk arrangements, and we even had a go at Mozart's Requiem, which is so marvellous! Unfortunately a virus damaged my right recurrent laryngeal nerve five years ago, and that was that - no more singing or public speaking. That really sucks, as you can imagine. So I still sing a bit in the shower; singing is good for the soul, and attempting scales, especially with mmmm and nnnn sounds, is actually helpful voice therapy. Basically, one of my vocal cords just sits frozen in a half-open position and the other one has to work overtime to try to compensate and make any sort of speech possible. There's a theory that you are more likely to get nerve repair if you keep doing stuff like that. At any rate, it kind of exercises the area.
