Afterward I saw a few paintings by Rembrandt, and all at once I was overwhelmed with the genius of the man that could convey so much thought in form and color. Then I saw a few landscapes by Corot, and I began to think I knew something about art. During all my life, of course, like other people, I had heard what they call music, and I had my favorite pieces, most of those favorite pieces being favorites on account of association; and nine-tenths of the music that is beautiful to the world is beautiful because of the association, not because the music is good, but because of association.. We cannot write a very poetic thing about a pump or about water works; they are not old enough. We can write a poetic thing about a well and a sweep and an old moss-covered bucket, and you can write a poem about a spring, because a spring seems a gift of nature, something that cost no trouble and no work, something that will sing of nature under the quiet stars of June. So, it is poetic on account of association. The stage coach is more poetic than the car, but the time will come when cars will be poetic, because human feelings, love's remembrances, will twine around them, and consequently they will become beautiful. There are two pieces of music, "The Last Rose of Summer," and "Home Sweet Home," with the music a little weak in the back; but association makes them both beautiful. So, in the "Marseillaise" is the French Revolution, that whirlwind and flame of war, of heroism the highest possible, of generosity, of self-denial, of cruelty, of all of which the human heart and brain are capable; so that music now sounds as though its notes were made of stars, and it is beautiful mostly by association.
