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.
