Tubas

The tuba (Latin, "trumpet"; ; ) is a large brass instrument in the bass-to-contrabass range with a wide conical bore. It usually has four or five valves, although some models have three and some have six. It first appeared in 1835 in Prussia as the , by adding five valves to a large 12-foot bugle pitched in F. This design provided a fully chromatic contrabass instrument with a deep, full timbre. By the 1850s, Paris instrument designer Adolphe Sax had developed the E and B band tubas with piston valves as part of his saxhorn family, and in the 1870s Václav František Červený in Austria-Hungary d

The euphonium ( ; ; ) is a tenor- and baritone-voiced valved brass instrument pitched in 9-foot (9) B an octave below the B trumpet or cornet, employed chiefly in brass, military, and concert bands. As with any brass instrument, sound is produced with a lip vibration or "buzz" in the mouthpiece. The euphonium is a member of the large family of valved bugles, along with the tuba and flugelhorn, characterized by a wide conical bore. Most instruments have four valves, usually compensating piston valves, although instruments with four or five rotary valves are common in Eastern and Central Europe.

The sousaphone ( ) is a brass musical instrument in the tuba family. It was first created around 1893 by J. W. Pepper as a modification of the helicon, at the direction of American bandleader John Philip Sousa, after whom the instrument was named. Sousa intended the bass sound of his helicons to better project above the heads of the band, and into the auditorium. Like the tuba, sound is produced by moving air past the lips, causing them to vibrate or "buzz" into a large cupped mouthpiece. Like the helicon, the modern instrument is bent in a circle to fit around the body of the musician, a
