Achille-Claude Debussy was a French composer. Along with Maurice Ravel, he was one of the most prominent figures associated with Impressionist music, though he himself intensely disliked the term when applied to his compositions.
The application of the term "impressionist" to Debussy and the music he influenced is a matter of intense debate within academic circles. One side argues that the term is a misnomer, an inappropriate label which Debussy himself opposed. In a letter of 1908, he wrote "I am trying to do 'something different'—an effect of reality ... what the imbeciles call 'impressionism', a term which is as poorly used as possible, particularly by the critics, since they do not hesitate to apply it to [J.M.W.] Turner, the finest creator of mysterious effects in all the world of art."
