potential drum majors to showcase their abilities and for the band director to choose who is head drum major. For bands that require auditions for the band, drumline, or auxiliary, auditions may happen the first few days for placement. Band camp usually lasts 1–2 weeks, but in the case of a more advanced marching band, camp may last up to a month. In most university bands, band camp means an earlier move-in date for university students in the band. American football games Marching bands serve as entertainment during American football games, which may also be known as pep band. For college and high school marching bands, this is the primary purpose of the ensemble. The home team's band plays the national anthem before kickoff (often as part of a pre-game show), as well as other music while in the stands during the game. Bands cheer with the cheerleaders, and some bands create their cheers. Marching bands then perform a show during halftime. When both teams' bands are present, it is a common protocol for the visiting band to perform first. After halftime, some high school bands use the third quarter of the game to take a break and get food. College bands and some high school bands do not have such breaks but continue playing in the stands during the entirety of the game. The band often stays the entire game, playing the school's fight song and alma mater at the end of the game regardless of the outcome. Three National Football League teams designate an official marching band: the Washington Commanders, Buffalo Bills and Baltimore Ravens. Marching bands were once common fare during Super Bowl halftime shows during its earlier years but were later replaced by short stadium rock concerts from high-profile recording artists, some of which have incorporated marching bands into their performances. Marching bands are otherwise uncommon at the professional level. Competition In competition, marching bands are usually judged on criteria such as musicality, uniformity, visual impact, artistic interpretation, and the difficulty of the music and drill. Competition exists at all levels but is most common in the U.S. among secondary school bands and drum and bugle corps. Performances designed for a competition setting usually include more esoteric music (including but not limited to adaptations of modern orchestral pieces). Many traditional-style bands compete in contests known as a Battle of the Bands, similar to the Atlanta Classic
