alright. So.
I gotta ask....
how high are you (were you?)
also, just to actually answer the question, if it's played as an instrument, it's an instrument. Anvils have been instruments (See that thing in Andor. that's an instrument.) Saws, too. Wine glasses. (both, by playing the rim, as well as breaking them as a sort of percussive instrument.). Even your desk when you're bored out of your skull waiting for that one email to come in so you can do your job. (rapatap tap, smack rapatap tap, thunk.)
Have you considered finding events at your local public library?
they may not have anything necessarily furry related, but mine at least has a lot of incredible events and social meetings. Yours probably has something that piques your interest.
What you're looking for is a "Third Space"- and libraries are a great third space.
