The euphoniumThis euphonium has a conical bore meaning the pipe gradually gets larger throughout the instrument. It also includes a large bell and 3 or sometimes 4 valves. A drawback of the four valve version is its cost but it allows for easier reaching of notes (a larger range) and a better tone.

The baritone |
The baritone in many ways is the same as the euphonium. One large difference is that the euphonium has a conical bore while the baritone has a cylindrical bore meaning the pipe stays around the same size throughout the instrument. The baritone still makes nearly the same sound but slightly higher and plays the same notes as the euphonium. It can also be four or three valves. The baritone also has a smaller bell than the euphonium.
The double bell euphonium |
Invented in the 1880's in the United States. It is essentially the same as a four valve euphonium. Of course, there is a weight difference. These euphonium can have four or five valves. The second bell is activated when the fourth or fifth key is pressed in. A famous band called the John Phillip Sousa band used this instrument. Its use in the band is probably the highest point in the double bell euphonium's life. The last series of double bell euphonium were produced in the 1960's.
