Marching euphoniums are used by [[marching band]]s and in [[Drum and bugle corps (modern)|drum and bugle corps]]. Typically in a drum corps, there will be two baritone parts and one euphonium part, with the euphonium playing the lower parts comparatively. Some corps (such as the [[Blue Devils Drum and Bugle Corps|Blue Devils]]) march all-euphonium sections rather than only marching baritone or a mix of both.<ref>{{Cite book|last=Legget|first=John A.|url=https://ttu-ir.tdl.org/bitstream/handle/2346/10257/31295019541480.pdf?sequence=1|title=Aspects for Arranging for Drum Corps: It's All About the Music!!!|year=2004}}</ref> In high school marching bands, the two will often be used interchangeably.

Depending on the manufacturer, the weight of these instruments can be straining to the average marcher and require great strength to hold during practices and performances, leading to nerve problems in the right pinky, a callus on the left hand, and possibly back and arm problems. Marching euphoniums and marching baritones commonly have three valves, opposed to the regular euphonium having four.

Another form of the marching euphonium is the convertible euphonium. Recently widely produced, the horn resembles a convertible tuba, being able to change from a concert upright to a marching forward bell on either the left or right shoulder. These are mainly produced by Jupiter or Yamaha, but other less expensive versions can be found.
