Mclean's concert band program is divided into three main ensembles: the Concert Band, the Wind Ensemble, and the Symphonic Band (the school's premiere band). McLean also has two award-winning jazz bands under the direction of Scott Weinhold and a chamber winds program led by Deidra Denson, which performed at Music For All's 2018 Chamber Music National Festival in Indianapolis. McLean High School also has a marching band. Once the annual show is determined and created, the marching band practices for over 250 hours to achieve a final product. In both 2016 and 2017, the McLean Highlander Marching Band won the title of Virginia State Champions.
