The Concert Band is a group that performs various genres of music at two performances, winter and spring, onstage in the Ridgewood Avenue Auditorium, and one performance connected to a competition and a trip. In 2013–2014, there are fifty-nine students in the Concert Band playing a variety instruments: alto saxophone, baritone saxophone, tenor saxophone, clarinet, bass clarinet, bassoon, oboe, flute, trombone, trumpet, French horn, tuba, percussion, and violin. (In the years to come, the district hopes to be able to fund a string ensemble as part of the high school music program.)
The music director selects the music, which tends to focus on band transcriptions of orchestral pieces. Recent selections include the Festive Overture by Dmitri Shostakovich, the Incantation and Dance by John Barnes Chance, Suites Numbers 1 and 2 for Military Band by Gustav Holst, and works by Elliot Del Borgo and David Holsinger as well as various other orchestral transcriptions. The director has also included Sousa and other traditional band pieces in the repertoire.
Students enter the Concert Band in seventh grade, rising from the upper elementary school music program. Students interested in joining the concert band do not audition or need to have prior skill on an instrument.
The Concert Band is considered an academic subject in Glen Ridge High School. The class meets one period a day during the school year. During the period, the band practices music and also learns music theory, rhythm, and instrument techniques. Before each concert, there are four early-morning rehearsals.
