Question: is a baritone a tuba?
Answer: In the British Brass Band Tradition, the Baritone is a member of the Saxhorn family, whereas the Euphonium is a member of the Tuba family. The Euphonium has a wider bore and a more conical flare over more of the instrument's length, compared to the smaller, shorter Baritone flare. ... If it fits, it's a Baritone.
