the tuba is a member of what instrument family
Tuba The tuba (UK: /ˈtjuːbə/ or US: /ˈtuːbə/;[1] Italian pronunciation: [ˈtuːba]) is the largest and lowest-pitched musical instrument in the brass family. Like all brass instruments, sound is produced by moving air past the lips, causing them to vibrate or "buzz" 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.[2] Tuba is Latin for 'trumpet'.[3]
Orchestra The typical symphony orchestra consists of four groups of related musical instruments called the woodwinds, brass, percussion, and strings (violin, viola, cello and double bass). Other instruments such as the piano and celesta may sometimes be grouped into a fifth section such as a keyboard section or may stand alone, as may the concert harp and electric and electronic instruments. The orchestra, depending on the size, contains almost all of the standard instruments in each group.
