Tuba vs. Sousaphone – What’s the Difference?


While similar in certain respects, the sousaphone and tuba have their differences. One of the most confusing things, however, is that the sousaphone is classed as being part of the tuba family. So how are the two different?

The sousaphone stems from the United States, in which John Philip Sousa wanted an instrument that sounded like a tuba but was able to project over a marching band. It also needed to be easy to play whilst on the go. So, to make the sousaphone portable, its body is designed to wrap around the player.

The tuba, on the other hand, provides a more focused sound that’s ideal for orchestras.

In this article, we discuss tuba vs. sousaphone, looking at their construction, sound, and what they’re used for. We’ll also give you some recommendations for each instrument, in case you’re in the market for one!

Tuba vs. sousaphone 

Shape and size

Student Eb Tuba by Gear4musicThe sousaphone is circular and designed to wrap around the player, making it ideal for marching bands. Its bell is forward-facing and can reach up to 32 inches, giving it a larger appearance.

In contrast, the tuba is more compact and typically used in orchestras. Its bell points upwards or to the side, providing a different kind of sound projection. Although the tuba is smaller and more versatile for various musical settings, the sousaphone’s design makes it perfect for outdoor and mobile performances. 


Sousaphones and tubas are traditionally made from brass as this is an incredibly durable material that provides a rich sound.

However, sousaphones can also be constructed from fibreglass for a lighter weight, making them easier to carry during performances. The choice of materials affects their weight, sound quality, and suitability for different performance settings.

Sousaphones and tubas differ in tunings and sound. Tubas are commonly pitched in BB, CC, EE, or F, and feature a smaller bell, providing a focused sound. An extra valve on the tuba extends its lower bass range, enhancing its versatility in orchestras.

Sousaphones, usually pitched in BB, have a larger, forward-facing bell, creating a brighter tone suited for marching bands. 

Where sousaphones and tubas are played

With its forward-facing bell, the sousaphone projects sound effectively over loud crowds, making it ideal for marching bands and parades. Its brighter tone helps it cut through the large sounds of jazz brass bands and marching ensembles.

On the other hand, the tuba has a focused sound and lower bass range, making it a versatile instrument that’s suitable for orchestras, jazz bands, brass ensembles, and concert bands. It can blend seamlessly into pretty much any musical setting and provide a great bass.
