or field band. A marching band review (parade) begins like a field show. Because of the street setting, there are usually no change in formations. Scoring is similar to a field show, however there is an added section specifically on the drum major's performance. The drum major is scored based on the execution of the opening routine, salute routine, beating time, vocal, whistle, and hand commands, and overall control of the band. To see one to three drum majors in most ensembles is typical. In some ensembles, drum majors switch positions during the show to allow all individuals a chance to conduct from the central podium. Occasionally, they may also serve in other capacities such as performing a solo, in which case one or two band directors would conduct the band temporarily until the drum major(s) would finish their/his/her solo. A marching band or drum corps drum major (field conductor) is in charge of holding the band or corps together, and directing the entire band or corps during shows and competitions. This drum major can come from any section of the performing unit: percussion, winds, or color guard. They are chosen on their musical abilities, leadership qualities, attitude, and passion for the sport. The Drum Major is the highest-ranked band participant, usually followed by the captain(s) of the drumline, then by guard captain(s), pit captain(s) horn sergeant(s), section leaders and band officers. In military bands, such as the Fightin' Texas Aggie Band or Highty-Tighties, drum majors are senior officers who are responsible for discipline and order of the band off the field, in addition to performance duties. They often command the band as an independent unit even off the playing field, and are treated according to their rank. In these bands, drum majors also march on the field and frequently use maces. Uniforms are in traditional military style; consequently, drum majors are distinguished by rank and unit insignia or distinguishing uniform modifications. For example, a drum major of the aforementioned Aggie Band could be recognized by his prominent wear of a whistle and chain, which is worn with the uniform even when not performing band-related duties. (Similar clothing in other bands may include sashes, unique headwear, or differently colored uniforms.) An example can be seen here. High school Based on how large the band is, high school marching bands have anywhere from one to four drum majors who are responsible
