The Morton High School Pep Band performs throughout the winter sports season for both girls and boys basketball games. The band is made up of members that volunteer their time to perform at 10 games throughout the year. This ensemble focuses of performing fun, energetic, popular music that ROCKS the Potter Dome! This ensemble has open instrumentation for electric bass, guitar, as well as other more "popular" instrumentation. Students must be enrolled in a second semester concert band to participate in Pep Band.

Information about Pep Band is sent out after the marching band season. This ensemble is co-led by Craig Hatter and Robert Hornsby.
