The Goldberg Variations - alongside Wohltemperiertes Klavier, Musikalisches Opfer, Die Kunst der Fuge - constitute the most intense link of Bach's art of polyphony. Thus, they focus on the whole essential problem of polyphonic composition using the counterpoint technique, on the problem of the polyphonic composition given to perform. In none of Bach's other works, these two moments - the composer and the executive - are so closely connected, almost identifying with each other. This work, originally for harpsichord, is at the same time the most pianistic of all Bach's keyboard works. This subtle interpretation of the Variations is performed by Professor Won-Sook Hur, one of the most recognized pianists in Korea, and should interest every fan of composer and didactic Bach craftsmanship.
