Music is an integral part of the curricular and co-curricular program at Westbourne. Students acquire musical knowledge and skills through classroom participation, individual lessons or many large and small music groups. Involvement in the School's music program helps develop the student's aesthetic, creative, spiritual and cultural potential.

The various musical groups within the School perform regularly in the local community. Concerts are a regular feature of the School calendar, providing an opportunity for students to gain experience in performing for an audience whilst at the same time enriching the cultural life of the School.

The music block includes four music classrooms, a large open area and a piano laboratory. The music centre contains an administration area and library, 16 teaching/practice studios and ready access to a 700 seat auditorium.

Students are exposed to both sacred and secular music with styles ranging from classical through to pop, rock and jazz.

A school musical production is staged each year which is a combined effort of both the Music and Drama Departments. The production involves a large number of students and staff in many months of preparation and rehearsal, and plays for a number of nights in the School Auditorium.
