Peter Tranchell composed this 1958 Sonata for Organ (his second) for, and partly based on the name of, Peter Le Huray, a fellow lecturer in the Music Faculty of Cambridge University, and Director of Music at St Catharine’s College.

The Carol Voluntary is a light-hearted piece with a serious side, melding eight different carols (at the last count) with unexpected results. It was first written for Tranchell's friend David Isitt (later The Reverend) in 1948, then revised in 1964.

The full anthem Cantantibus organis for St Cecilia’s Day was written by Peter Tranchell in 1987 for use by the choir of Gonville and Caius College, Cambridge, where he was Precentor (Director of Music), and it was sung at Evensong (presumably on St Cecilia’s Day, 22 November) that year. It was written for S.A.T.T.B. and Organ.

People, look East was composed in 1982 for the Gonville and Caius Choir and originally scored for AATBrBB (though with a note on the cover saying 'If necessary, the first alto part may be sung by sopranos'). The version performed by St. John's College Choir in the 2015 Advent Carol Service was arranged for SATB by Peter Marchbank in 2013.

Peter Tranchell set this famous text (from Edward Fitzgerald’s version of Rubáiyát of Omar Khayyám of Naishápúr) to music in May 1978, shortly before the death of Geoffrey Thornton, the Caius Chapel organ scholar who succumbed to melanoma. Peter knew it was inevitable and although there's nothing on the score it was conceived very much as an In Memoriam.

Peter Tranchell composed the Five Thackeray Ditties for the Cambridge University Madrigal Society’s May Week Concert in June 1962, which was conducted by Raymond Leppard. The concert traditionally took place on the Backs with the choir in punts on the Cam while the audience sat on the riverbank.
