A euphonium is the second largest instrument in the brass family. It is described as having a ‘sweet and dark’ sound. This instrument has a baritone voice and is played with valves, but should not be confused with a baritone horn.

 The euphonium and the baritone differ in size. The baritone is a cylindrical bore instrument, which gives a brighter sound, whereas the euphonium has a conical bore, giving a mellower sound. However the technique and range of these instruments are identical, making it easy for musicians to switch between the two.

The shape of this instrument is similar to a tuba, only smaller. It can be played sitting down with the bell facing up.

Euphoniums are pitched in B♭ and are used in a number of musical genres including school bands, marching bands, concert bands and orchestras. A euphonium can play in the bass clef and the treble clef in concert pieces.

The euphonium is typically a band instrument and is often used for a solo. In some orchestral music the euphonium plays the part of tenor tuba, as orchestral pieces are not usually written for euphoniums.
