=== Drum and Bugle Corps ===
[[Drum Corps International|Drum Corps International (DCI)]] is the governing body for competitive junior drum and bugle corps in North America, showcasing elite marching ensembles made up of performers aged 13 to 21. Known as "Marching Music’s Major League," DCI hosts nationwide competitions culminating in the annual World Championships.<ref>{{Cite web |title=About Drum Corps International (DCI), Marching Music’s Major League™ |url=https://www.dci.org/static/about-drum-corps-international |access-date=2025-05-05 |website=www.dci.org |language=en}}</ref>

There are typically five brass instruments: the [[trumpet]] (soprano voice), the [[mellophone]] (alto voice), the baritone (tenor/baritone voice), the euphonium (baritone voice), and the [[Contrabass bugle|contrabass]] (bass voice). The baritone within these ensembles is often known as the '''marching baritone,''' used in both college and high school [[marching band]]s. They have three valves and a front-facing [[Bell (wind)|bell]] and are pitched in the key of Bb, similarly to the baritone.

These horns originally started as a lower-voiced bugle. Eventually they started adding valves to the bugles, which were only allowed to be in the key of G. First came a single horizontal piston, then 1 piston and 1 rotor, 2 pistons, and finally 3 pistons.<ref>{{Cite web |title=G Bugles |url=https://tiffanyjohns.com/blog/g-bugles |access-date=2025-05-05 |website=Tiffany Johns |language=en-US}}</ref> In current day, there is a combination of different corps which use either the [[marching euphonium]], marching baritone, or both, typically having around 24 members in the section. `
