Adam Schmidt you’re right, I wouldn’t. This comment I made was kinda stupid, thank you for correcting me. For tuba, we don’t puff our cheeks unless we’re playing with bad tone really loud, mainly used for a couple marching band pieces. My only point, and only correct thing I said was that you should not be puffing your cheeks if you’re not playing loud/blatting. I’ve heard some beginner tubas at my school do it, and I do correct them and tell them that you can do it sometimes, but only in certain scenarios.
SinisterMinister about your comment, once again. Hurting your mouthpiece should usually be a no go. I expect you to know that, what Mnozil brass did right now was for fun, and putting their instruments at risk. It would never break your instrument, but no one likes getting their mouthpiece lodged in there
Mouthpiece puller. Any sane brass player has one for just in case. The old ones, like mine from the 1970s were just slightly modified mechanical gear pullers. Now they makes ones customized for trumpets, etc. Benefit of my old one is will work for all brass instruments.
