List of compositions by Malcolm Williamson
This is a list of the compositions of Malcolm Williamson. It is sorted chronologically by genre. Cassations. Williamson used the word "cassation" in the sense of a miniature opera including audience participation. He wrote ten such works, of varying complexity and duration. His primary intention was to teach children the mechanics of putting on an opera, and the idea for the pieces first came to Williamson while teaching his own children about music. Williamson had a great deal of success with these cassations, which have had performances in Britain, Australia, France, the USA, and  in hospitals in Tanzania and Zambia. Chamber music. [the String Quartet No. 1, subtitled "Winterset", which dates from 1947–48, remains unpublished.] Unfinished works. Williamson left a number of works unfinished at his death. These include a Strindberg-based opera "Easter" (with a libretto by Myfanwy Piper), a Symphony No. 8 "Agamemnon" (based on the poem by Dame Iris Murdoch), and sketches for a Piano Concerto No. 5, which he had hoped to write for his Australian friend, the pianist Antony Gray.
