Music is part of the curriculum throughout the school and all boys are encouraged to begin or continue learning a musical instrument.

The subject is increasingly popular at GCSE and A-level and there are also numerous opportunities to pursue musical projects outside of the classroom, including the school Big Band, Junior Orchestra, Joint Symphony Orchestra, Chamber Orchestra, Choir and String groups. The school has also collaborated with Lancaster Girls' Grammar School to produce large scale musicals such as "Oh What a Lovely War!" and "The Little Shop of Horrors", "My Fair Lady", "North and South" by Julian Davies and Harvey Rycroft, "South Pacific", "West Side Story", "Gentlemen Prefer Blondes", "The Threepenny Opera", "Cabaret" and "Les Miserables" and "Grease". In fact, a musical is performed each year in the Grand Theatre, Lancaster.

A European tour is usually undertaken each year. Most recently the Chamber Orchestra gave concerts in Vienna and Salzburg, the Big Band in Vienna, Salzburg, Krakow, Rendsburg and Keil and the choir in Tampere (Finland) and Rendsburg (Germany). Following the Chamber Orchestra tour the group went on to win the National Final of Music for Youth staged in the Royal Festival Hall, London.
