What is the difference between a tuba and sousaphone?

The tuba and the sousaphone are both large, low-pitched brass instruments. They are both played by blowing air through a mouthpiece that causes a column of air inside the instrument to vibrate. However, there are some key differences between the two instruments.

Size and Shape

The tuba is the larger of the two instruments. It typically stands about 6 feet tall and weighs between 25 and 50 pounds. The sousaphone is about 5 feet tall and weighs between 20 and 35 pounds. The tuba is also more cylindrical in shape, while the sousaphone has a more conical shape.

Sound

The tuba has a lower pitch than the sousaphone. The tuba's lowest note is the CC, while the sousaphone's lowest note is the BBb. The tuba also has a more resonant and powerful sound than the sousaphone.

Usages

The tuba is used in a variety of musical settings, including orchestras, concert bands, and jazz bands. The sousaphone is primarily used in marching bands and brass bands.
