Definition of BRASS INSTRUMENT
: any of a group of wind instruments (as a French horn, trombone, trumpet, or tuba) that is usually characterized by a long cylindrical or conical metal tube commonly curved two or more times and ending in a flared bell, that produces tones by the vibrations of the player's lips against a usually cup-shaped mouthpiece, and that usually has valves or a slide by which the player may produce all the tones within the instrument's range
Musical wind instrument, usually made of brass or other metal, in which the vibration of the player's lips against a cup- or funnel-shaped mouthpiece causes the initial vibration of an air column. The trumpet, trombone, French horn, tuba, euphonium, sousaphone, cornet, flügelhorn, and bugle, as well as historical instruments such as the ophicleide, cornett, and serpent, are considered brass instruments (though the last two were made of wood); the saxophones, though made of brass, are reed instruments classified as woodwind instruments.
