In my second year of playing, my violin had a bit of a problem. I live in Minnesota and the weather here is insane. Especially in the winter. It will be warm one day, and thirty below freezing the next. Anyways, I was going to school one morning and it was super cold outside, but warm inside. So the weather change from my house, to outside, to the school was harsh on my violin. when I unpacked my violin hours later at school I found my violin in pieces. Not like the wood cracked, but the pegs fell out, the end button and tail piece fell off, the strings came off, and the sound post even tipped over. Anyways, I fixed it and I’ve gotten a new violin since then and pay better attention to humidity problems.
