2台のピアノのための協奏曲
The Princesse de Polignac now became an important musical patron in her own right. She established a prize in music in her husband's name, and commissioned Igor Stravinsky's "Renard", Manuel de Falla's "El retablo de maese Pedro", Erik Satie's "Socrate", Francis Poulenc's Concerto for Two Pianos and Orchestra and Organ Concerto (Poulenc), and Germaine Tailleferre's Piano Concerto. She also subsidized individuals and organizations, such as Nadia Boulanger, Clara Haskil, Arthur Rubinstein, Vladimir Horowitz, Ethel Smyth, Adela Maddison, the Ballets Russes, the Paris Opera and the "Orchestre Symphonique de Paris". Until 1939, the Polignac salon was the foremost gathering-place for the artistic elite in Paris and Venice, including Jean Cocteau, Claude Monet, Sergei Diaghilev and Colette.
