Do you know what tuba is? I will tell you a little about my experience in playing this instrument.
The tuba is used in marching band performances to fill in the bass range. Like most brass instruments used in marching band performances, this instrument has also been designed to be played while walking with the mouthpiece facing forward. However, it is different from other musical instruments, because of its large size, to play this musical instrument is carried out on the shoulder.
In my opinion, this tool is very difficult to play, I have to spend a lot of energy because this tool is very heavy.
