Like his predecessor Chopin, Debussy discovered new possibilities and refinements in the art of playing and composing for the piano. His compositions and transcriptions for piano four hands are among his most inventive and interesting works. This volume contains Marche Ecossaise, written specifically for piano four hands, and the composer's transcription for four hands of La Mer. These works display both the brilliant pianism at the heart of Debussy's musical imagery and the composer's affinity for the unexpected -- a quality that allowed many of his compositions to unfold like highly sophisticated improvisations. Reprinted here from authoritative French editions, they will challenge and delight pianists with their unique qualities.
