The baritone and euphonium have eight main parts as labeled below (euphonium). They are made from brass and are very similar, with the main difference being the shape. A baritone has a smaller bell than a euphonium and the tubing is the same diameter throughout. The tubing is the same length as the euphonium but it is more tightly wrapped, making the instrument a bit more complact and easier to hold. The euphonium is slightly wider and heavier, and also requires a larger lung capacity than the baritone, making the baritone a better suited choice for beginners.
