Who does not know the Chaconne by Jean-Sébastien Bach, the piece that closes his Partita in D minor for solo violin? The composers constantly tried to appropriate this exceptional piece for other instruments. The most famous arrangement is certainly that of Ferruccio Busoni. Without straying too far from Bach's original, Busoni adapted the virtuosity of the violin to the possibilities of the keyboard instrument, thus succeeding in creating a piano piece that takes advantage, just as brilliantly, of the resources offered by the modern piano. In addition to traditional sources, we have, for our Urtext edition, examined for the first time in such depth a piano roll, on which we hear Busoni himself. The fingerings are from the pen of none other than Marc-André Hamelin.
