Fantasia contrappuntistica

Fantasia contrappuntistica (BV 256) is a solo piano piece composed by Ferruccio Busoni in 1910. Busoni created a number of versions of the work, including several for solo piano and one for two pianos. It has been arranged for organ (by Wilhelm Middelschulte, dedicatee of the work, whom Busoni praised as "Meister des Kontrapunktes") and for orchestra (by Frederick Stock) under the composer's supervision.

The work is in large part a homage to Johann Sebastian Bach's Die Kunst der Fuge. Conversely, Kaikhosru Shapurji Sorabji's Opus clavicembalisticum appears to be a homage to Fantasia contrappuntistica.
