These transcriptions go beyond literal reproduction of the music for piano and often involve substantial recreation, although never straying from the original rhythmic outlines, melody notes and harmony. This is in line with Busoni's own concept that the performing artist should be free to intuit and communicate his divination of the composer's intentions. Busoni adds tempo markings, articulation and phrase markings, dynamics and metronome markings to the originals, as well as extensive performance suggestions. In his edition of Bach's "Goldberg Variations" (BV B 35), for example, he suggests cutting eight of the variations for a "concert performance", as well as substantially rewriting many sections. Kenneth Hamilton comments that "the last four variations are rewritten as a free fantasy in a pianistic style which owes far more to Busoni than to Bach."
