The church has enjoyed a fine reputation for music since its early days, maintained high-quality professional music for much of the last century. There have been distinguished organists, including Edwin Lemare, Walter Alcock and john Ireland (1879-1962) the great English composer of church music (including Greater Love, and My song is love unknown) as well as instrumental and orchestral works (including the Epic March)

A full choir for Sunday services has been maintained from the completion of the present building in 1890 with the exception of a decade in the 1970s when Holy Trinity fell on hard times. Since a revival in the late 1980s, choral music has thrived once again thanks to the efforts of a succession of choirmasters.

Holy Trinity Choir, a professional quartet, sing on most occasions and are supplemented by four choral scholars on two Sunday mornings per month, as well as at major feast days and festivals.

Since 2016, the introduction of Choral Evensong and Benediction on Sunday evenings has further expanded the repertoire and the range of musicians who participate.

Apart from Sundays, most festivals are observed with a Sung Eucharist and carol services are held at Christmas and the Epiphany with a Sequence of Music and Readings on Palm Sunday evening.

On All Souls’ Day there is a Sung Requiem with music by Duruflé or Fauré and on Trinity Sunday all the church’s musicians come together for a Sung Eucharist and Procession to celebrate the Feast of Title.
