IMPRESSIONISTIC METHODS--DEBUSSY AND HIS INFLUENCE
IMPRESSIONISM as developed by Claude Achille Debussy ( 1962-1918) was one of the strongest factors in the creation of a different and non-Teutonic mode of thought in music.

He won the Prix de Rome in 1884 with his cantata L'Enfant Prodigue, and again his natural tendency to revolt against any
