Editing Baritone horn (section)

== Differences between the Baritone and Euphonium ==
Although both baritone and euphonium produce partials of the B{{music|flat}} harmonic series in the same range, and both have a nine-foot-long main tube, the baritone tends to have a smaller and more cylindrical bore than the euphonium which is more conical. The baritone usually has a tighter wrap and a smaller bell, and is thus smaller and lighter overall, and produces a "lighter" and more direct sound versus the more solid, round timbre of the euphonium.<ref name="The Instruments of Music" /><ref name="Harvard Dictionary of Music">{{Cite book|last =Apel|first=Willi|year =1972 |orig-year= 1969| title = Harvard Dictionary of Music|pages = 105–110|place=Cambridge |publisher = Belknap Press of Harvard University Press}}</ref>

There is a common misconception that the three-valved instrument is a baritone and that the four-valved instrument is a euphonium. Euphoniums often have a fourth valve as an alternate fingering for 1 & 3 split fingering with improved intonation. The fourth valve can also be viewed in the same way as an F trigger on trombone, re-pitching the instrument to expand the lower range. A fourth valve is less common on baritones, but absence of a fourth valve is not a defining characteristic.<ref name="confusion_bari_euph">{{cite web|last1=Werden|first1=David|title=Baritone or Euphonium?|url=http://www.dwerden.com/eu-articles-bareuph.cfm|publisher=dwerden.com|access-date=8 June 2015|ref=confusion_bari_euph}}</ref>

An "American baritone", featuring three valves on the front of the instrument and a curved forward-pointing bell, was common in American school bands throughout most of the twentieth century. While this instrument is in reality a conical-cylindrical bore hybrid, neither truly euphonium nor baritone, it was almost universally labeled a "baritone" by both band directors and composers.<ref name=confusion_bari_euph />
