Debussy’s ideas on piano playing

Norwegian Composer Karstein Djupdal collected several original sources about Claude Debussy’s ideas on piano playing, attempting to reconstruct what it could be Debussy’s own piano method. Debussy was very exigent about the performances of his own music, and he was often critical towards pianists who did not understand the sense or the expression of his scores. He left several comments for other pianists, including Ricardo Viñes and Marguerite Long, who often played his music for him. The sources are books, articles and reminiscences by pianists, pupils and friends of Debussy as well as Debussy’s own letters and writings.
