Bliss studied under Ralph Vaughan Williams and Gustav Holst. Up to the early 1920s, his music was frequently experimental, e.g., Rhapsody (1919), for solo voices and chamber ensemble, in which the voice plays an instrumental role, singing vocalises (meaningless syllables), and A Colour Symphony (1922, revised 1932), whose four movements are intended to suggest the colours purple, red, blue, and green. Later, although he never abandoned experimentation, he began composing in classical forms, e.g., the quintets for oboe and strings and for clarinet and strings, the Piano Concerto, and the Conversations for chamber orchestra. He composed the scores for three films, including Things to Come (1935; after H.G. Wells). Other works include the television opera Tobias and the Angel (1960) and his choral symphony Morning Heroes (1930). His ballets are Checkmate (1937; choreographed by Ninette de Valois), Miracle in the Gorbals (1944; choreographed by Robert Helpmann), and Adam Zero (1946; Helpmann). His last composition, a choral work called Shield of Faith, was performed initially a few weeks after his death, at the 500th anniversary celebration at St. George's Chapel, Windsor. Bliss was knighted in 1950 and in 1953 became Master of the Queen's Musick.
