Hi Sophie, welcome to the group.

Having played a bard for a while I can tell you any expensive instrument is in some danger if you're carrying it around. However I had a small celtic lap hard that managed to survive unscathed, as long as I didnt bring it near any battles. Usually smaller things like flutes or ocarinas (or your voice) are better for that setting, and more expensive instruments are better saved for performing at the inn. I hope that helps!
