One orchestral work by this composer opens with a sustained timpani roll and double bass tremolo on a low B, while two harps alternate playing octave F-sharps and G-sharps. Some of this composer's piano works were orchestrated by André Caplet. At the opening of one piece by him, an F - A-flat third in the pianist's left hand is answered by the same third an octave above in the right hand. That movement in D-flat major and 9/8 time appears in a piano suite by him that ends with a "Passepied". The movement "Play of the waves" is the second in a series of three "symphonic sketches" by him, depicting the ocean. For 10 points, name this French composer of La mer, whose Suite bergamasque includes the movement "Clair de Lune".
