for piano and two percussion The title of the work, Wu Ji, comes from ancient Chinese philosophy: "Wu" means "nothing" or "the lack of." "Ji" means "polarity" or "infinity," that which is beyond time and space; its presence precedes that of anything in the universe. (The percussion instruments required are: marimba, tam-tam, high blocks, Chinese opera gongs, wing gong, crotales, mark-tree, bow chime, vibraphone, blocks.)
