what's your take on butterflies

you have to learn an new instrument, it doesn't matter if you already know an instrument (if you do, do tell me!) as this is a new instrument, which one do you choose?

(anyone who i might hove asked this question to: please ignore) what is your favorite minecraft block? preferably something that exists in modern and supported versions, but if your favorite minecraft block is a blue rose or nether reactor core i wont stop you.
