Thanks, Rapunzel!
I've been playing the violin for about 10 years - since I was 7 years old. Wow, you play quite a few instruments! I play the keyboard as well, but I'm not that good at it. Good luck with learning the violin - it can be tricky, but it's great fun, and you can play a lot of different styles of music with it.

About the tuning, did you ever keep your violin where it would get very hot or very cold? Extremes of temperature can send any string instrument out of tune (as I found out, when I kept my violin next to a radiator all night once...

). That's interesting, I didn't realise it was so easy to recognise another musician!
