I'm a highschool student, and iv just noticed as of lately that im biting too hard. since iv realized this, iv dropped down from superial 3.5 to about a D.C. 3. Now im facing the issue of readjusting my embouchure. Where should my bottom teeth be biting? I used to bite the skin below my lip for support, but iv noticed that i can't play past C4 like that. whenever i play an E4, i generally bite exactly where my lip is. but now im noticing that my lip is slipping off the reed. any suggestions?
