The sound of any brass instrument starts with buzzing your lips into a mouthpiece, which agitates the column of air inside the tube that makes up the instrument, causing vibrations in that air column which travel through the outside air as sound waves.
By buzzing your lips faster, you can force multiple waves inside the tube, so that (for example) two equal waves are occupying the tube instead of just one. Since this means twice as many waves are produced in the same amount of time, you have a higher frequency--thus a higher pitch (an octave higher, to be exact). There is a mathematical formula called the harmonic series that can plot the different frequencies (notes) that can be produced by this "overblowing" method.
The other way you change pitch on a brass instrument is by changing the length of the tube--shorter air column, higher pitch; longer air column, lower pitch. Trombones do this the easy way--they have a slide which, the further you push it out, the longer the tube, thus the lower the pitch. This wouldn't be very practical for a tuba or sousaphone (though it would be fun to watch), so instead they have valves (usually three on a sousaphone) that redirect the airflow through extra bits of tubing to make the air column longer and thus lower the pitch.
Between the two--changing the speed of lip-buzzing, and using valves (or a slide) to change the length of the tube--the brass instruments are able to cover all the notes of the chromatic scale.

Is a fiberglass sousaphone heavier than a brass sousaphone?
yea
Is there such thing as a tsungi horn?
no, there's not. the instruments that come close in terms of appearance to the tsungi horn from avatar the last airbender are the sousaphone and the french horn. the actual sound of the tsungi horn in the cartoon is produced by the duduk, a double reeded instrument from Armenia.
Is tubas and sousaphone same?
They're similar. The sousaphone is a marching version of the tuba.
What is a tuba like instrument?
Baritone horn, Sousaphone, Euphonium, Contrabass bugle, and Alto Horn
What family does sousaphone belong to?
Brass
Which instrument was the predecesssor of the sousaphone?
The helicon was the predecessor of the sousaphone. It was a large, circular-shaped brass instrument with the bell facing forward, designed for marching bands. The sousaphone was developed to improve the portability and projection of sound while marching.
How do you use the helicon?
The Helicon is of the same sound and operation as that of the Tuba, and Sousaphone. It is basically interchangeable.

Is gun sound and smoke produced at the same time?
The smoke is produced slightly before the sound. Smoke is produced by the ignition of the propellant in the round. The sound is produced when the bullet passes through the sound barrier.
