Tuba
The tuba (UK: / ˈ tj uː b ə /; US: / ˈ t uː b ə /) is the largest and lowest-pitched musical instrument in the brass family. As with all brass instruments, the sound is produced by lip vibration – a buzz – into a mouthpiece. It first appeared in the mid-19th century, making it one of the newer instruments in the modern orchestra and concert band, and largely replaced the ophicleide. Tuba is Latin for " trumpet ".

A person who plays the tuba is called a tubaist, a tubist, or simply a tuba player. In a British brass band or military band, they are known as bass players.
