Musical Instruments ( III ) BRASS

BRASS

Brass instruments are simply brass tubes, narrow at one end and gradually widening until it reaches the bell. They are coiled or bent in some way for easy handling. Some common brass instruments are trumpet, horn, trombone and tuba. Same as wind instruments, tone is produced by blowing breath in the tube, however the pitch is determined by a specially shaped mouthpiece. Slack lips produce low notes while tight lips produce high notes. The quality of tone produced depends on the shape of the mouthpiece. Shallow cup-shaped mouthpiece as used in trumpet forms higher harmonics and brilliant tone. Horn, which use deeper funnel-shaped mouthpiece sounds more mellow.
