Wind Instrument Brief Introduction



Wind Instrument Brief Introduction


A wind instrument is a musical instrument that contains some type of resonator (usually a tube), in which a column of air is set into vibration by the player blowing into (or over) a mouthpiece set at the end of the resonator.


The pitch of the vibration is determined by the length of the tube and by manual modifications of the effective length of the vibrating column of air. In the case of some wind instruments, sound is produced by blowing through a reed; others require buzzing into a metal mouthpiece. Wind instruments are typically grouped into two families: brass instruments (horns, trumpets, trombones, euphoniums, and tubas) and woodwind instruments (recorders, flutes, oboes, clarinets, saxophones, and bassoons).


Although brass instruments were originally made of brass and woodwind instruments have traditionally been made of wood, the material used to make the body of the instrument is not always a reliable guide to its family type. A more accurate way to determine whether an instrument is brass or woodwind is to examine how the player produces sound. In brass instruments, the player's lips vibrate, causing the air within the instrument to vibrate. In woodwind instruments the player either causes a reed to vibrate, which agitates the column of air (as in a clarinet, oboe or duduk), blows against an edge or fipple (as in a recorder), or blows across the edge of an open hole (as in a flute).
