When I play in the lower to middle register, I drop my lower jaw and move it forward so that my upper and lower teeth are directly opposite each other and about ¼ to ½ inch apart. I am comfortable with this and believe it to be a good way of playing.

However, as I go into the higher register, my tongue rises (“Eeee”) and I tighten my corners. As I do this, my lower jaw pulls back to a more normal position, with my lower teeth behind my upper teeth. Because of this, the bell drops about an inch in order to maintain even mouthpiece pressure on my lips.

The gap between my teeth appears to stay the same but my lower lip rolls in and nearly touches my top teeth.

Is this wrong? Should I continue to move my jaw forward in the upper register and try to keep my upper and lower teeth directly opposite each other?



Thanks
