eccentric English composer known for his complex musical works combining free rhythms, elements of Asiatic melodic construction, and European polyphonic structures.

Dudley was of Parsi, Sicilian, and Spanish descent and spent most of his life in England. As a young man he became interested in his father's Parsi heritage and changed his name accordingly. He began his career as a masterly concert pianist, but he abandoned concert performing in the early 1920s. In the 1920s and '30s he was an outspoken music critic and essayist, displaying biting wit and sarcasm in his critical evaluations. He then took up composition.

Sorabji's most famous composition is Opus Clavicembalisticum (1930). It consists of one movement lasting nearly 5 hours and is the longest nonrepetitive piano composition ever published. He wrote several symphonies, including the “Jami” Symphony (1942–51), which was nearly 1,000 pages long. From 1940 to 1976 Sorabji prohibited the performance or further publication of his works, making them available only in his own private recordings. In 1976 he permitted only Michael Habermann and Yonty Solomon to perform his works. His books include Around Music (1932) and Mi Contra Fa: The Immoralisings of a Machiavellian Musician (1947).
