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 horn is played left-handed with the bell facing backwards. The tuba is the lowest in pitch of the brass instruments, and it can be built to sit on the player's lap, or wrap around the player's body. To unlock this lesson you must be a Study.com Member.
