The tuba (UK /ËtjuËbÉ/ or US /ËtuËbÉ/ ; [ËtuËba]) is the largest and lowest-pitched musical instrument in the brass family. Sound is produced by vibrating or buzzing the lips into a large cupped mouthpiece. It first appeared in the mid 19th-century, making it one of the newer instruments in the modern orchestra and concert band.
The brass section of the orchestra is known for its brilliant and blazing sounds. Brass instruments are usually made of metal tubes with a cylindrically shaped mouthpieces. The notes that come out of the bell shaped end are produced when the air column within vibrates.t is the highest pitched of the brass instruments. Normally two or three are used in a symphonic orchestra for that reason. The tone of the tuba is much deeper than the trumpet due to the large size of the instrument and its tubing system.
