Busoni wrote the Divertimento in May 1920, four years before his death and while the unfinished Doktor Faust occupied him. He planned it as one half of a diptych with the Concertino for clarinet of 1918, and thought it the more fantastic, more masculine and shorter of the two; the music, he said, came to him as easily as writing a letter, and the score was done on 24 May. It runs about nine minutes in three contrasting sections, with a Mozartian brilliance in the solo part. The dedicatee was the flautist Philippe Gaubert.
