This playlist is compiled after the list of works on the composer's site, and sorted in reverse chronological order; from Speakings (2008) to Dialogue (1965). Two undated works (The Tree & Ah! Sun-Flower) are included at the end. For newcomers, I recommend to start with the String Quartets, Bird Concerto With Pianosong and White as Jasmine.
