Embouchure

Embouchure (English: ) 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 or brass instrument. The word is of French origin and is related to the root bouche, 'mouth'. Proper embouchure allows an instrumentalist to play an instrument at its full range with a full, clear tone and without strain or damage to their muscles.
