The school choir, under the musical direction of Ms Caroline Hearns, enriches the many liturgical events that take place throughout the school year. With over 70 members, it performs at the Mass for the opening of the school year, advent services, the annual carol service and Lenten services. The 6th year members of the choir also perform at the 6th year Graduation Mass in May.
The school choir also participates in the annual Emmanuel programme organised by the Archdiocese of Dublin to promote new liturgical music in post primary schools. The highlight of the programme is the performance in the Helix Theatre.
