Woodwind and brass musical instruments are wind instruments, in which sound is produced by the action of the player's breath as he or she blows into the instrument. The family of woodwind musical instruments consists of flutes, clarinets, oboes, bassoons, and saxophones. All of the instruments in this family contain a vibrating reed or reeds in the mouthpiece, with the exception of the flute. The sound of a modern transverse flute is made by the action of the player's breath directly against an edge. Other types of flutes, such as recorders, use a whistle-like mouthpiece. The pitch of woodwind instruments is varied by opening and closing holes in the body of the instrument.
Woodwind instruments are usually purchased for band or orchestra use (e.g., for a student to play as part of a school band or orchestra). Brass instruments are also used as band and orchestra instruments. The tone of a brass instrument is produced by the vibration of the player's lips as the player's breath passes through a tubular resonator.
Brass instruments include trumpets, French horns, trombones, tubas, and other horns. Many brass instruments (such as the trumpet) use valves operated by the player's fingers to change the length of instrument's tubing, and thus its sound. A smaller number of brass instruments, such as the trombone, use a slide to achieve the same purpose.
Woodwind brass musical instruments may be purchased new or used. The best source of information for novice buyers on choosing the best new or used woodwind brass instruments or brass woodwind vintage instruments for their needs is the advice of experienced musicians, music teachers, and dealers.
