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 from the movie Drumline. There are also competitions at the national level, such as the Bands of America (BOA) Grand National Championships through Music for All.
