Busoni embodied an essentially recreative approach to the music of the past. His Bach transcriptions reveal an absolute command of intricate polyphony and a limpid clarity. Mozart stood as an aesthetic and technical exemplar while Cramer’s little-known Etudes are adapted for modern piano technique. Busoni preserved the Lutheran austerity of Brahms’s Chorale Preludes for Organ, Op. 122 whereas in the Mephisto Waltz No. 1 he augments Liszt’s heady writing with a super-virtuosity of his own.
