Façade is a series of poems by Edith Sitwell, best known as part of Façade – An Entertainment in which the poems are recited over an instrumental accompaniment by William Walton. The poems and the music exist in several versions. Sitwell began to publish some of the Façade poems in 1918, in the literary magazine Wheels. In 1922 many of them were given an orchestral accompaniment by Walton, Sitwell's protégé. The "entertainment" was first performed in public on 12 June 1923 at the Aeolian Hall in London, and achieved both fame and notoriety for its unconventional form. Walton arranged two suites of his music for full orchestra. When Frederick Ashton made a ballet of Façade in 1931, Sitwell did not wish her poems to be part of it, and the orchestral arrangements were used. After Sitwell's death, Walton published supplementary versions of Façade for speaker and small ensemble using numbers dropped between the premiere and the publication of the full score in 1951.

A piano quartet is a chamber music composition for piano and three other instruments, or a musical ensemble comprising such instruments. Those other instruments are usually a string trio consisting of a violin, viola and cello. Piano quartets for that standard lineup were written by Wolfgang Amadeus Mozart, Robert Schumann, Ludwig van Beethoven, Johannes Brahms, Antonín Dvořák and Gabriel Fauré among others. In the 20th century, composers have also written for more varied groups, with Anton Webern's Quartet, opus 22 (1930), for example, being for piano, violin, clarinet and tenor saxophone, and Paul Hindemith's quartet (1938) as well as Olivier Messiaen's Quatuor pour la fin du temps (1940) both for piano, violin, cello and clarinet. An early example of this can be found in Franz Berwald's quartet for piano, horn, clarinet and bassoon from 1819, his opus 1. A rare form of piano quartets consist of two pianos with two players at each piano. This type of ensemble is informally referred to as "eight-hand piano", or "two piano eight hands". Eight-hand piano was popular in the late 19th century before the advent of recordings as it was a mechanism to reproduce and study symphonic works. Music lovers could hear the major symphonic works all in the convenience of a parlour or music hall that had two pianos and four pianists. Many of the popular works of Mozart, Schumann, Brahms and Dvořák were transcribed for two piano eight hands. The majority of 8 hand piano music consists of transcriptions, or arrangements.

William Walton's String Quartet in A minor was his second work in the genre. He withdrew an early attempt, premiered in 1922, and wrote the A minor quartet between 1944 and 1947. It was first given in a BBC radio broadcast on 4 May 1947 and received its first public performance the following day. In 1971, at the instigation of the conductor Neville Marriner, Walton orchestrated and revised the work as his Sonata for String Orchestra.
