Baritones and euphoniums are usually made of brass or other metal, and usually silver-plated or lacquered. Baritones and euphoniums are small tubas. The baritone sounds in the same range as a trombone. Baritones and euphoniums are found in concert and marching bands, and occasionally in the orchestra. Baritones and euphoniums also often play solos.

The baritone and euphonium come in many different designs. Orchestral and concert band instruments are held upright. Marching instruments have a bent mouthpiece pipe so that the weight of the instrument can be supported on the shoulder. Baritones and euphoniums have always had valves because they were invented after valves were.

The baritone is very similar to the euphonium. The euphonium is usually larger bored and is related to the flugelhorn. The baritone is more closely related to the cornet. Baritones usually have three valves, while euphoniums often have four or five.

On a baritone or euphonium, the sound is made by the buzzing the player's lips. The mouthpiece helps the sound become clearer. The rest of the instrument makes the sound louder. Any fingering on the instrument can make many different notes so you need to have a good ear for music to know if you are playing the right note.
