With an embouchure like that used for a brass instrument, the musician holds the mouth of the jug about an inch from their mouth and emits a blast of sound, made by a buzzing of the lips, directly into it.

On a capped double-reed instrument the function of the mouthpiece is simply to provide a chamber within which the reed can vibrate, with a hole through which air can be blown. On a fipple flute the mouthpiece, or fipple, provides a shaped passageway for air to be blown against an edge, producing turbulent flow which excites the resonant vibrational modes of the air column. A pirouette is a wooden mouthpiece
