Richard Rodney Bennett, the British composer who in a long, distinguished career moved with ease among classical concert music, jazz and film, died Dec. 24 in New York, where he had lived since 1979. He was 76.
His death was confirmed by his sister, Meg Peacocke.
"Richard Rodney Bennett: The Complete Musician" was the title of a 2010 biography, and few other figures in the arts have had so plausible a claim to distinction in such diverse genres.
Mr. Bennett wrote three symphonies, 17 concertos, five operas and dozens of elegant chamber works in a style that fused the avant-garde theories of Pierre Boulez, one of his teachers, with his own flexible, lyrical, nondogmatic approach.
He was an accomplished jazz pianist and singer who wrote and performed both songs and large-scale pieces. Three of his roughly 50 film scores were nominated for Academy Awards: "Far From the Madding Crowd" (1967), "Nicholas and Alexandra" (1971) and "Murder on the Orient Express" (1974), which won a BAFTA award, the British equivalent of the Oscar, in 1975.
His taste had this wide range from the time he began listening to music on the radio as a child.
"When I came across something I liked," Mr. Bennett said in an interview with The Guardian in 2011, "I wanted to find out as much as I could about it. This was as true of hearing Hoagy Carmichael for the first time as it was later when I first heard Mr. Boulez. Being on a musical quest was something I always enjoyed."
Richard Rodney Bennett was born March 29, 1936, in Kent, England, and grew up in Devon, where his family moved at the outbreak of World War II. It was a household receptive to artistic inclinations: his father wrote children's books, and his mother was a pianist who had once studied composition with the British composer Gustav Holst.
Mr. Bennett's musical talents were clear early on. In a telephone interview Ms. Peacocke said that he began playing the piano around the age of 3. He first began writing down music -- "lots and lots of what looked like arpeggios," she said -- around 4. By 7 he was creating intelligible, playable pieces.
"I just scribbled away and eventually a C major chord was there," Mr. Bennett recalled. By the time he was 18 he had written three string quartets, and a year later he had finished his first film score.
He entered the Royal Academy of Music in London in 1953 and by his first summer had begun to attend the groundbreaking composition courses held in Darmstadt, Germany, where the participants included Luigi Nono and Karlheinz Stockhausen and the aesthetic ideology was uncompromisingly 12-tone. A scholarship from the French government gave Mr. Bennett two years of study in Paris with Mr. Boulez, another Darmstadt stalwart.
Mr. Bennett was appointed a Commander of the Order of the British Empire in 1977 and was knighted in 1998 for his service to music.
