For some reason, the mouthpiece seems to dig in a little in one spot on my chops, the left side (under the rim) of my upper lip. It looks normal enough when I play, but I don't have the same cushion in that part of the chops. The longer I keep the horn on my face, the worse it is. I don't have any crooked or protruding teeth, my mouthpiece is pretty much centered, and my bell points a little down. I think it may be bacause my jaw slides a little to the right when I play. Tonight I was playing some long tones and moving my jaw to the center seemed to balance out the pressure pretty well. I moved it very slightly...probably barely visible. It was more of a feel thing that a postiion thing, if that makes any sense. My question is, is that the right approach? To try to balance out the pressure while playing something simple and let it work it's way into the rest of my playing? I'd love to hear any thoughts about how to deal with this. Thanks! Jason.
