Saxophone Embouchure – it is the connection between you and the horn that helps express the sound you want.
The tenor sax embouchure or bari sax embouchure is made slightly easier if you have a more square jaw since the mouthpiece is larger. Metal and hard rubber mouthpieces also have different shapes. So find what is comfortable for you.
