ASAP answer clarinet experts help! Hi guys. I play the clarinet, and I just found out today on my upper joint, there is this thin bar thing sticking out from the side. It is almost about to come out, but I am afraid to take it off because I feel like the whole side will collapse. Does anyone know what that is, and will it be safe if I take it off? I have attached a picture. Thank you! I need an answer ASAP because my concert is in a few days, and need to know if it is serious or not.
