Peter Tranchell's Sonatina for pianoforte (1949) is a little mysterious - Tranchell didn't mention it in letters home, and was at the time talking more about his piano concerto (which either never materialised or has been lost). Two versions of the Sonatina exists in the CU archive; one bearing the dedication "For Jane" is presumed by Peter Marchbank to be the definitive version.

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.
