Mouthpiece (brass) Mouthpiece (brass) On brass instruments the mouthpiece is the part of the instrument placed on the player's lips. The mouthpiece is a simple circular opening that leads, via a semi-spherical or conical cavity, to the main body of the instrument. Mouthpieces vary to suit the tone of the instrument. Lower instruments also have larger mouthpieces, to maximize resonance (see pitch of brass instruments). Also, mouthpieces are selected to suit the embouchure of the player, to produce a certain timbre, or to optimize the instrument for certain playing styles. For example, trumpet and trombone mouthpieces are usually semi-spherical whereas French horn
Woodwind instrument then split; this causes the column of air within the closed flute to vibrate and produce sound. Examples of this type of flute include the recorder, ocarina, and organ pipes. Reed instruments produce sound by focusing air into a mouthpiece which then causes a reed, or reeds, to vibrate. Similar to flutes, Reed pipes are also further divided into two types: single reed and double reed. Single-reed woodwinds produce sound by placing a reed onto the opening of a mouthpiece (using a ligature). When air is forced between the reed and the mouthpiece, the reed causes the air column in
