There are several levels of choirs at the school in Summer Hill, New South Wales. The task of the Chapel Choir is to present music of the finest quality that will set the tone of the worship within the Chapel. The Schola Cantorum Choir is open to all boys with broken voices.
The Trinity Canticus Choir serves as the foundation of the Choral Programme at Trinity. It is a large auditioned Choir of treble voices consisting of boys from Years 7, 8 and 9. The Choir performs in its own right, as well as augmenting the Chapel Choir and Schola Cantorum for large choral works.
The Trinity Singers were formed in 1980 by their present director, James Southwood. The aim was to create an auditioned choral group of excellence, which would be the leader for all other musical groups in the Preparatory School.
They have achieved an enviable reputation among the Independent Schools' community and are regarded as one of the leading boys choirs in Australia. In the Eisteddfods in which they have participated over the years, the Singers have never come less than first. They are regularly invited to perform at festivals, concerts and various charity and community events. The Singers have made four recordings so far, the last being a CD and are conducted by Mr. James Southwood.
