The award-winning Prosper High School Mighty Eagle Marching Band is one of the largest student organizations on campus with over 350 students involved. Musicians and Color Guard in 9th, 10th, 11th, and 12th grades make up one of the premier 6A bands in the nation. All musicians in Marching Band must be enrolled in one of the PHS concert bands.
Students are able to earn a P.E. and/or fine arts credit through their participation. The Marching Band season begins with Spring Training Sessions, which includes incoming 9th grade students, just prior to the end of the school year. Band Camp begins in late July with daily sessions running to the first day of classes. Weekly before or after school rehearsals start the first week of classes, and the Marching Band performs at all football games. All participants are required to attend all rehearsals and performances.
The Marching Band performs in several competitions on fall Saturdays in local contests, UIL, and Bands of America circuits.
