Question

What's the difference between a baritone horn and a Euphonum?

Answer 1

its the same just they have two names

Answer 2

There is a huge difference: Baritones are a cylindrical bore instruments and euphoniums are a conical bore instrument. Basically, a cylindrical bore is shaped like a cylinder through more of its length and a conical bore is shaped like a cone.

Acoustically the instruments produce sound waves very differently (this is really too complex to get into here, but it has to do with the way the waves reflect between the bell and mouthpiece, also with how the waves deform in a conical bore). The audible result is conical bore instruments like the horn, tuba, and euphonium have a darker, richer sound, and cylindrical bore instruments, like the trumpet, trombone, and baritone are brighter.

Baritones are INCREDIBLY uncommon in the United States. They are pretty much used in Europe. Most "baritones" that are seen in the states are, in fact, euphoniums.

Answer 3

They are pretty similar. Baritones tend to have a narrower bore and smaller bell, they are also mainly cylindrical. Euphoniums have a larger bore and bell and are typically conical.
Euphoniums also tend to have four valves and therefore more tubing, although this can also apply to baritones.
