The part of a wind instrument that is placed in, on, or by the performer's mouth

A "mouthpiece" is an essential component of certain musical instruments, particularly those in the brass and woodwind families. It is the part of the instrument that the musician blows into or places their mouth on to produce sound. The design and construction of the mouthpiece significantly affect the instrument's tone, playability, and overall sound quality.

In brass instruments such as trumpets, trombones, and tubas, the mouthpiece is typically a detachable component that attaches to the instrument's lead pipe. It consists of a metal cup-shaped piece with a small opening, known as the rim, where the musician's lips make contact. The size and shape of the cup, along with the rim contour, throat, and backbore, contribute to the instrument's response, intonation, and tone color.

Woodwind instruments like the clarinet, saxophone, and flute also have mouthpieces. These mouthpieces are usually made of materials such as hard rubber, plastic, or metal. They feature a facing, which is a curved surface where the musician's lips come into contact, and a reed or an embouchure hole through which the player blows air to produce sound. The design and dimensions of the mouthpiece impact the instrument's intonation, projection, and tonal characteristics.

Choosing the right mouthpiece for an instrument is crucial for musicians. Different mouthpieces can provide variations in tone quality, articulation, and overall playing comfort. Musicians often experiment with various mouthpiece designs and sizes to achieve the desired sound and playing experience.
