Alongside the “Chaconne” for violin, the ten “Chorale Preludes” for organ are Busoni's best-known piano transcriptions of works by J. S. Bach. Unlike the “Chaconne,” which Busoni envisaged for concert performance, he transcribed the “Chorale Preludes” in “chamber-music style.” A great deal of this organ/piano edition can also be played by advanced amateurs. Henle is publishing Busoni's definitive version in the first modern Urtext edition with valuable fingering suggestions by Marc-André Hamelin. And what is more, in the appendix they are publishing an eleventh chorale prelude for the first time: Busoni's transcription of “Aus tiefer Not.” With regard to performing its six-part setting, the composer himself spoke of an “extreme performance limit” – but why not judge for yourself!
