step and music selections are largely based on R&B, hip-hop, and contemporary popular music. In addition to traditional drill formations, HBCU bands feature heavily choreographed dance routines as part of their performances. Many of these bands may have a twirler line or a dancer line, but not necessarily flag twirlers. One of the most notable depictions of HBCU bands is the 2002 film Drumline. The history of African American marching bands was explored through a 2018 exhibition called "Marching On: The Politics of Performance" in New York City. HBCU bands are a significant part of African American musical culture and HBCU bands often surpass their associated football teams in popularity, a phenomenon that is uncommon among collegiate and high school marching bands. In 1989, as part of the celebrations for the bicentennial of the French Revolution, the Florida A&M University Marching 100, one of the most prolific HBCU bands in the country, was selected as the official representative of the United States in the bicentennial parade. Another style of show band is that used by many of the Big Ten Conference marching bands, a semi-military and semi-corps style. These bands perform a show that is designed to entertain the audience but feature more traditional symphonic styles of music (marches, film scores, jazz, or older pop music) as well as some contemporary music. Big Ten style show bands have been influential in creating some of the earliest marching band innovations, and the style is used in high schools throughout much of the United States. Most show bands of either type include the traditional military band instrumentation of woodwinds, brass, and battery percussion. Some also include the front ensemble keyboard percussion and may also incorporate the use of a color guard for flag, and rifle routines as well as a dance line. Carnival bands Carnival bands are a United Kingdom variant of show bands. Carnival bands typically march in time to the music and may also participate in parades and competitions. They contain brass and percussion, but may or may not use woodwinds. Scramble bands Scramble bands (also referred to as 'Scatter' bands) are a variation on show bands. They generally do not march in time with the music, but, as their name implies, scramble from design to design and often incorporate comedic elements into their performances. Most of the bands in the Ivy League use this style, excepting only Cornell University.
