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.
This instrument was soon adopted by British brass bands. Tubas come in a number of keys: BB flat, CC, E flat, F, and GG, though the tuba is what is called a non-transposing instrument, as its music is read and played in concert pitch. There are many design configurations for the tuba.
