a low brass instrument with 3 or 4 valves that can be played in treble or bass clef. hardly anybody knows what it is so euphonium players often get tired of explaining it. they are usually the least ignorant section in low brass and the smallest and most talented section in the band.
band director: can someone please explain the coda to the trombones!?
euphonium section: we can! we can!

n. a large 3- or 4-valved brass instrument resembling a small tuba; it is similar to the baritone horn but, while the baritone has a cylindrical (straight) bore, the euphonium has a conical (grows larger as it progresses towards the bell) bore, warming up the sound

When you pick up a girl, ram her vagina, attempt to stick the small end of a euphonium mouth piece into her nipple, and continue to play on the mouth piece, representing her body as a euphonium.

Euphonium is basically a tuba, but instead of being a god-like instrument, they decided to make it bad.
Guy#1: Hey, do you know how cool the tuba is?
Guy#2: Yeah?
Guy#1: Let's NOT make the euphonium like that.

Absolute worst instrument in the world, go play tuba, or any other instrument. This crap is the worst instrument to start on. If you play this instrument, switch to tuba this instant.
