The euphonium looks like a small tuba, but has a higher pitch and mellower sound. Its name comes from the Greek and means "sweet voiced" or "beautiful sound." The outstanding quality of the euphonium is its deep, rich tone quality. The instrument is made of brass, can have anywhere from three to five valves and has conical tubing. The euphonium's brother, the baritone, has cylindrical tubing, is smaller and has a brighter, lighter tone.
