the tuba is the largest member of which musical 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]
Eustachian tube The Eustachian tube /juːˌsteɪ.ʃən/, also known as the auditory tube or pharyngotympanic tube,[1] is a tube that links the nasopharynx to the middle ear. It is a part of the middle ear. In adult humans the Eustachian tube is approximately 35 mm (1.4 in) long and 3 mm (0.12 in) in diameter.[2] It is named after the sixteenth-century anatomist Bartolomeo Eustachi.[3]
