Editing Trombone (section)

==== 20th-century wind bands ====
During the first half of the 20th century the popularity of touring and community concert bands in the United States decreased. At the same time, the development of music education in the public school system made high-school and university concert bands and marching bands ubiquitous. A typical concert band trombone section consists of two tenor trombones and one bass trombone, but using multiple players per part is common practice, especially in public-school settings.{{Citation needed|date=March 2020}}
