Herz, Thalberg, Heller, Felicien David and others were great virtuosos of their time, more famous than Chopin himself. They had their own personal styles, but the essence of their music was time-bound, nothing that could occupy generations after them. Chopin, in contrast, was someone special, someone who was completely different from all other artists, composers, and pianists. So too with his style. As a result, the aesthetic in approaching Chopin is distinctive: interpreting his music is the most difficult of all. For me personally, it's the crowning of playing piano. Bach, Mozart, Chopin: these are the three who definitely created musical art in an all-embracing and overwhelming way.
