I'm kinda bored with just sticking to one instrument. I want to learn another one on the side just as a hobby(Which is weird because I consider piano to be a very serious hobby). The instruments I don't want would be: violin(hard for people to listen to, so it would be a no-no at home), cello/contrabass(anything large), saxophone.
I'm open to all other instruments.
Edit: Classical music instruments only, sadly =\
