During a rehearsal i played my euphonium upside down (which is much harder than it sounds), and also bouncing on my knee, which made it sound like constant trills. Band director didnt notice. He never notices anything i do tbh

i’ve always wanted to do something like that tbh. either put it on my knee or see how much my hand can go into a tuba or something.
