Hello everyone. I have a problem with my embochure that I currently play "in the red", meaning you can see the red of my lip at the top of the mouthpiece, which is apparently a serious issue that no one has addressed with me until now. I am in my first year of college and am in marching band, pep band , and next semester i am in either university band or concert band. I tried to not necessarily fix it, but messed with it in a practice room by doing lip slurs and long tones. After I was well warmed up this weird thing happened where I would try to do slurs and lip bends and my mouthpiece would slip back into the old playing style. I've talked to many people about this and some say I have to change it, and others say if it isn't broken, don't fix it. So what do you all think? any specific exercises I should do to fix the problem or should I just leave it since my tone, range, and style are pretty on par with a collegiate band? any comments appreciated.
