Apart from his work on the music of Bach, Busoni edited and transcribed works by other composers. He edited three volumes of the 34-volume Franz Liszt Foundation's edition of Liszt's works, including most of the etudes, and the "Grandes études de Paganini". Other Liszt transcriptions include his piano arrangement of Liszt's organ "Fantasy and Fugue on the chorale "Ad nos, ad salutarem undam"" (BV B 59) (based on a theme from Giacomo Meyerbeer's opera "Le Prophète") and concert versions of two of the "Hungarian Rhapsodies".
