I got another bass clarinet from my new school. I kept making squeaking noises, and I don't know why. 1. The ligature is not loose enough to reach the bottom of the mouthpiece. 2. The neck is not tightening to the body, keeps to swinging around...
Does anyone know what might have caused the squeaking? The bass clarinet is suuuuper old and no one had cleaned it for a while now, so it's hard to find the cause.
I didn't find the right solution from the Internet.
