euphornism, pronounced (you-for-knee-ism) is the feeling you get when you post a well written document, make a delicious sandwich, or create an amazing animation that has you wanting to run around a lot and boosting your confidence, but at the same time has you wanting to do something with your life

overall, this is the best feeling you could get.

euphonium

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

The euphonium has a dark, rich sound--except when too much garbage has been dropped down the bell.
