The activities of Trinity’s Music Department, at Preparatory, Junior, Middle and Senior levels, are vigorous and exciting, offering a diverse range of opportunities from work in the classroom, through group and individual instrumental tuition, to co-curricular activities for larger groups, including original compositions some of which are used by other arts disciplines such as film, dance and drama. Music is an essential element of the School’s curriculum. Most boys will at some stage learn a musical instrument and engage in group musical activity, such as choir, orchestra, band or ensemble, or a musical stage production.

Trinity Grammar School is renowned for its encouragement of music. The Music Department has one of the most dynamic and impressive Performance programmes both in New South Wales and Australia and, in terms of student participation, is one of the most comprehensive. Commitment of students and staff to achieving excellence in the area of performance has earned them an impressive reputation. Senior performance groups are sought by many organisations outside the school.

A great deal of the music at Trinity Grammar School takes the form of a rich variety of practical music making, both in and outside the timetable. The Instrumental Programme is well developed and for students who show a particular aptitude and inclination, additional instrumental tuition in orchestral, band, vocal and keyboard instruments is provided as an extension of the formal class music. Throughout the music curriculum students explore music through practical performance and composition, and begin to appreciate the diversity, heritage and wealth of the world’s music.
