Part of the Brass family, the Euphonium speaks as the tenor voice and is pitched in Bb. Often times confused with the baritone, the euphonium has a significant difference. The use of conical tubing where the instrument gradually goes from smaller to larger tubing (like a cone) is used on a euphonium. In fact, many parents and band directors will use the term baritone and euphonium somewhat interchangeably.
The sound of the euphonium is very distinct, commonly found as the counter-melody in many John Philip Sousa marches along with classic pieces by Holst. The combination of soaring tone above the ensemble and virtuosic technical ability the valves provide makes the euphonium a double threat both as an ensemble instrument and a solo instrument. Another common application for the modern euphonium is the British Brass Band where the euphonium again holds a key position in the ensemble sound. Musicians such as Steven Mead have made the euphonium commonplace in any brass instrument discussion.
