The baritone horn is a brass instrument that produces a rich, warm sound. It is similar in appearance to a tuba but is smaller and has a more compact shape. The instrument typically has a conical bore, which helps create its distinctive tone, and is often used in concert bands and brass ensembles. Baritone horns are played using a mouthpiece and have three to four valves that allow the player to change the pitch. They are commonly found in marching bands and orchestras, contributing to the harmony and depth of the music. The instrument is sometimes confused with the euphonium, which has a similar range and sound.
