Two pianos heard the same scores; “Doctor Gradus ad Parnassum” and “The snow is dancing” composed by Master Debussy, “Nocturne cis-moll, Op. posth.” by Master Chopin at places of two families. One belongs to Mei-Shun’s elder sister, while Ms. Piano as the other of course. These two sisters used to practice on the former, a generous gift from their grandmother of mother’s side.
