The Hempfield Black Knight Marching Band consists of over 100 members. The Symphonic Band is for grades 10-12. The Concert Band is a 50+ performance group which accepts all levels of musicians from all grades, and is designed for 9th graders to adapt them to the more challenging material and style that is played in this band. The 2012-2013 band was selected to perform at the PMEA All-State conference. The Jazz Band hosts a variety of shows during the year, and the Jazz Lab Band performs with the Jazz Band during the spring jazz concert. All of the bands at Hempfield are supervised by the department chair of music, Matt Ceresini.
