The Belen bands program has over 200 student musicians and was established in January 2005. There are three major band units in the school: the jazz band, the concert band and the drum line. The Belen jazz band has won first and second place awards in competitions at Disney World, the Miami-Dade Youth Fair and the Festival of Music in Washington D.C. and Chicago. The bands have three annual concerts at the Roca Theater, while the drum line is a source of “mood and spirit” at pep rallies and athletic competitions. Sections of the bands do charity work during the Christmas season, performing in malls, assisted living facilities, and hospitals.
