A mouthpiece is the part of a musical instrument that comes in direct contact with the player's mouth to modify the sound produced by the instrument. Windway refers to the channel inside the fipple that directs the flow of air that produces the sound. Piston is another term used to describe a wind instrument's fipple because it controls the air entering the pipe, regulating the pitch and volume produced.
