Cooper is best known for his book French Music, first published in 1951. He was a lifelong enthusiast of Gluck and a champion of the often vilified Meyerbeer, Gounod and Massenet.[4] He was less forgiving of what he saw as the romantic excesses of Mahler, Strauss and Elgar.[5] But his interests were wide-ranging, encompassing German and Russian music, as well as a broader, cosmopolitan perspective on philosophy, literature and cultural and political history than most of his English contemporaries.[5][6]
He married the artist Mary Stewart in 1940. There were four children, including the novelist Dominic Cooper and the pianist Imogen Cooper.[7] Cooper was appointed CBE in 1972. In retirement he turned increasingly to translation, including the collected essays of Pierre Boulez and a new translation of Tchaikovsky's Queen of Spades.[5][8] He died in Richmond upon Thames.
