The Bach-Busoni Editions are a series of publications by the Italian pianist-composer Ferruccio Busoni (1866–1924) containing primarily piano transcriptions of keyboard music by Johann Sebastian Bach. They also include performance suggestions, practice exercises, musical analysis, an essay on the art of transcribing Bach's organ music for piano, an analysis of the fugue from Beethoven's 'Hammerklavier' sonata, and other related material. The later editions also include free adaptations and original compositions by Busoni which are based on the music of Bach.
Busoni issued his Bach editions over a nearly 30-year span in two collections: the 25-volume Busoni Ausgabe[1] (Joh. Seb. Bach Klavierwerke) and the Bach-Busoni Collected Edition (Bach-Busoni Gesammelte Ausgabe), which was first issued in 6 volumes in 1916, and subsequently in 7 volumes in 1920. A small collection of selected excerpts with transcriptions of organ and violin music was also published separately in 1916 as Sechs Tonstücke (Six Tone Pieces).[2][3][4]
