Brass

Brass

Brass instruments are measured lengths of hollow tubing, with a metal mouth piece which the player holds to his lips firmly while playing. By forcing breath through the lips, the instruments themselves vibrate or resonate and impulses are sent down the tubes. Flaring out with a sweep, the bell at the far end of the instrument's tube serves to project the sound. The tubing itself may be bent in circular form such as the cornet, French horn and tuba.
