Embouchure Embouchure Embouchure or lipping is the use of the lips, facial muscles, tongue, and teeth in playing a wind instrument. This includes shaping the lips to the mouthpiece of a woodwind instrument or the mouthpiece of a brass instrument. The word is of French origin and is related to the root "", 'mouth'. Proper embouchure allows instrumentalists to play their instrument at its full range with a full, clear tone and without strain or damage to their muscles. While performing on a brass instrument, the sound is produced by the player buzzing his or her lips into a mouthpiece. Pitches

They generally originate from the surface of the skull bone (rarely the fascia), and insert on the skin of the face. When they contract, the skin moves. These muscles also cause wrinkles at right angles to the muscles’ action line. The facial muscles are supplied by the facial nerve (cranial nerve VII),
