One of the most important instruments in the band. The tuba is the largest and lowest brass instrument and anchors the harmony for the whole band with its deep rich sound. You blow and buzz into a very large mouthpiece and use your hand to press down on the valves which changes the sound.

C,Eb, & F Tuba

Tubas can be found in various pitches, most commonly in F, E♭, C, or B♭. The main tube of a B♭ tuba is approximately 18 feet (5.5 m) long, while that of a C tuba is 16 feet (4.9 m), of an E♭ tuba 13 feet (4.0 m), and of an F tuba 12 feet (3.7 m).

Valve Tuba

The rotary valve design does not promote particularly fast response, but it includes a longer leadpipe which contributes to a beautiful smooth tone which blends well with other instruments.


The “big brother” of the tuba family, the sousaphone is used almost exclusively in marching bands. They produce solid sound and projection that is made of a lightweight fiber-reinforced plastic material to reduce fatigue during long performances.
