But it is not only the spirit of French classicism that Ravel and Debussy inherit. In one respect their art is the continuation of the music that came to a climax in the works of Haydn and Mozart. It is subtle and intimate, and restores to the auditor the great creative role assigned to him by so much of the music before Beethoven. The music of Haydn and Mozart defers to its hearer. It seeks deliberately to enlist his activity. It relies for its significance largely upon his contribution. The music itself carries only a portion of the composer's intention. It carries only enough to ignite and set functioning the auditor's imagination. To that person is reserved the pleasure of fathoming the intention, of completing the idea adumbrated by the composer. For Haydn and Mozart did not desire that the listener assume a completely passive attitude. They had too great a love and respect of their fellows. They were eager to secure their collaboration, had confidence that they could comprehend all that the music intimated, regarded them as equals in the business of creation. But the music written since their time has forced upon the hearer a more and more passive role. The composers arrogated to themselves, to varying extents, the greater part of the activity; insisted upon giving all, of doing the larger share of the labor. The old intimacy was lost; with Wagner the intellectual game of the _leit-motif_ system was substituted for the creative exercise. The art of Ravel and Debussy returns to the earlier strategy. It makes the largest effort to excite the creative imagination, that force which William Blake identified with the Saviour Himself. It strives continually to lure it into the most energetic participation. And because Ravel and Debussy have this incitement steadily in view, their music is a music of few strokes, comparable indeed to the pictural art of Japan which it so often recalls. It is the music of suggestion, of sudden kindlings, brief starts and lines, small forms. It never insists. It only pricks. It instigates, begins, leaves off, and then continues, rousing to action the hearer's innate need of an aim and an order and meaning in things. Its subtle gestures, its brief, sharp, delicate phrases, its quintessentiality, are like the thrusting open of doors into the interiors of the conscience, the opening of windows on long vistas, are like the breaking of light upon obscured memories and buried emotions. They are like the unsealing of springs long sealed, suffering them to flow again in the night. And for a glowing instant, they transform the auditor from a passive receiver into an artist.
