The baritone/euphonium (you-phone-ium) is a member of the brass family. As with all brass instruments, the sound is produced by buzzing the lips into a mouthpiece. The baritone works in the same manner as a trumpet but it’s twice the length. It plays the exact same notes as a trombone and even uses the same mouthpiece. The biggest difference is that the baritone uses valves rather than a slide to change the length of the air flow. The baritone is relatively easy to learn for beginners. The deep beautiful tone from a baritone is attractive to many students who like the sound of a lower voice. Many students who like the tuba start out on the baritone with plans to switch to the tuba after a year or two of band. The tuba is the same as a baritone in nearly every way. It’s just twice the length.
Euphonium players should have moderately full lips, but not too full. A SLIGHT overbite is okay, but an underbite would hinder a good sound. The euphonium requires a medium-sized hand size to reach the valves and students should have an above average lung capacity.
Students with braces could find the euphonium mouthpiece a bit more comfortable than trumpet or French horn.
