Embouchure

Embouchure is the shape of the mouth and the use of the muscles around the mouth on the mouthpiece of a wind instrument. Embouchure can change the timbre and pitch, so it is very important to control it.

The mouthpiece is a consumable item, and it naturally accumulates teeth marks, but a mouthpiece patch is one method of preventing this. However, when the teeth are making strong contact (i.e. there is a tendency to bite down), there may be a problem with the embouchure. With proper embouchure, the teeth are just touching the mouthpiece, and the muscles around the mouth are closing on the mouthpiece.
