The euphonium (you-PHONE-knee-yum) is sometimes known as the baritone. It is a member of the brass family and looks like a small version of a tuba. Its sound is similar to that of a trombone, but it uses valves like a trumpet instead of a slide (like trombone).
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 span to reach the valves and students should have an above average lung capacity.
Students with an above average amount of orthodontia will find the mouthpiece of the euphonium a bit more comfortable than trumpet or French horn. CTMS provides euphoniums for students at a cost of $100 rental for an entire school year, but students are required to purchase their own mouthpieces and supplies.
