The tuba (UK /ˈtjuːbə/ or US /ˈtuːbə/; Italian pronunciation: [ˈtuːba]) 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 tuba largely replaced the ophicleide. Tuba is Latin for 'trumpet'.A person who plays the tuba is known as a tubaist or tubist. In the United Kingdom a person who plays the tuba in an orchestra is known simply as a tuba player; in a brass band or military band they are known as a bass player.
