The Fairfax High School Choral Department consists of six ensembles: Women's Concert Choir, Men's Ensemble, Women's Chorale, Bel Canto, Voce, and the extra-curricular a cappella group Rebel Treble.  Approximately 140 students participate in the Fairfax choirs.  Fairfax choral students also participate in District Chorus, Virginia Honors Choir and All-State Chorus, as well as a regional competition trip in the spring.  Choral groups perform music of many periods and styles and develop musicianship through vocal technique, sight-reading, and basic music theory.  In addition to the choral concerts held at FHS, students have performed in the Fairfax musical, at the Fairfax Festival of Lights, the Fairfax City Band Concert, the New York City Festivals of Music, the Heritage Festival in Atlanta, GA, the Smoky Mountain Music Festival, and Festival Disney.
