Brass instrument Brass instrument A brass instrument is a musical instrument that produces sound by sympathetic vibration of air in a tubular resonator in sympathy with the vibration of the player's lips. Brass instruments are also called "labrosones", literally meaning "lip-vibrated instruments". There are several factors involved in producing different pitches on a brass instrument. Slides, valves, crooks (though they are rarely used today), or keys are used to change vibratory length of tubing, thus changing the available harmonic series, while the player's embouchure, lip tension and air flow serve to select the specific harmonic produced from the available series.

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
