The tuba (UK: /ˈtjbə/;[1] US: /ˈtbə/) is the 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. The tuba largely replaced the ophicleide.[2] Tuba is Latin for "trumpet".[3]
