Mozart’s graceful e minor sonata floats on the memory of his mother’s passing, Takemitsu’s threnody occupies the delicate space between sound and silence, and Debussy reaches the final stop on his harmonic revolution of beauty and light. Big-boned and dark-hued, Prokofiev’s sonata vacillates between the gale force intensity of his modernist spirit and sardonic wit and the eternal wind of profound introspection…without beginning or end.
