Darius Milhaud (French: [daʁjys mijo]; 4 September 1892 – 22 June 1974) was a French composer, conductor, and teacher. He was a member of Les Six—also known as The Group of Six—and one of the most prolific composers of the 20th century. His compositions are influenced by jazz and Brazilian music and make extensive use of polytonality. Milhaud is considered one of the key modernist composers.
Born in Marseille to a Jewish family from Aix-en-Provence, Milhaud began as a violinist, later turning to composition instead. Milhaud studied in Paris at the Paris Conservatory where he met his fellow group members Arthur Honegger and Germaine Tailleferre. He studied composition under Charles Widor and harmony and counterpoint with André Gedalge. He also studied privately with Vincent d'Indy. From 1917 to 1919, he served as secretary to Paul Claudel, the eminent poet and dramatist who was then the French ambassador to Brazil, and with whom Milhaud collaborated for many years, setting music for many of Claudel's poems and plays. While in Brazil, they collaborated on a ballet, L'Homme et son désir.
On his return to France, Milhaud composed works influenced by the Brazilian popular music he had heard, including compositions of Brazilian pianist and composer Ernesto Nazareth. Le bœuf sur le toit includes melodies by Nazareth and other popular Brazilian composers of the time, and evokes the sounds of Carnaval. The recurring theme is, in fact, a Carnaval tune by the name of "The Bull on the Roof" (in Portuguese which he translated to French 'Le boeuf sur le toit', known in English as 'The Ox on the Roof'). He also produced Saudades do Brasil, a suite of twelve dances evoking twelve neighborhoods in Rio. Shortly after the original piano version appeared, he orchestrated the suite.
