Euphonium, for the win.

The euphonium is an instrument, that no one seems to have heard of. Unless you are that amazing (or involved in music). It's my instrument. If you are unaware of what a euphonium is, it's kind of a mixture Between a tuba and a trombone (if it's a marching euphonium, it also mixes in a little trumpet). Often times the euphonium is mistaken for a baritone, because there is very little difference between them. A baritone does not have conical tubing, and a euphonium does. Conical tubing is when The tubing from the mouthpiece to the bell, the tubing gradually gets larger. So, in a baritone, the tubing is all the same size until the bell (where it must get larger). Someone with slight musical background might tell you that the difference between a baritone and a euphonium, is the fact that a baritone has three valves compared to a euphonium with four. That is incorrect. Baritones can have four valves, it's just more common for them to have three. I hope you feel more informed as to what a euphonium is. That would be the instrument that play, and it's not very common, which makes it 58times cooler.
