Chopin once said of himself that he was in this world like the E string of a violin on a contrabass. His finely-strung nature sought retirement, and fate had given him precisely that longing for rest and harmony which of necessity made the contrabass of this world excessively painful to him. He ran restlessly from one abode to another, till he found in the Place de Vendôme the best for dying in; he became more and more retiring, called for peaceful pearl-gray carpets, and gave full play to all his decorative emotions, which are the external proof of a harmonic soul. The art of his life was driven into isolation, into inclusion in the sacred recesses of his musical poems; and he knew well how so to level his life to the external observer, that the biographers--apart from his one great passion--had never so uneventful a life to record. The well-known description of an evening with the master, which Liszt gives in his fanciful but yet so true biography of Chopin, is so rich in character that reality itself could hardly have done it better. A melting twilight in the room, the dark corners seeming to produce themselves into infinity, the furniture covered with white hangings, no candle except by the piano and by the fireside. We distinguish Heine, Meyerbeer, the tenor Nourrit, Hiller Delacroix, the unemotional Minkiewicz, the gray-haired Niemcewicz, and George Sand with propped arm leaning back in a chair. The people stand round Chopin in the twilight, and hardly know whence these magic tones come. [The English reader will recall the exquisite description of Chopin’s playing in Crawford’s romance “With the Immortals.”] We can easily see why Chopin could never compose duets. Not only did he devote himself exclusively to the piano--he wrote nothing in which the piano does not bear a part--but he broke with the custom of writing duets for one or two pianos. A single Rondo for two pianos, of the year 1828, was found among his remains. How he smiled once at Czerny, who “had composed another overture for eight pianos and sixteen persons, and was very happy over it.” Chopin opened to the two hands a wider world than Czerny could give to thirty-two. And further, he selects and rejects with great care before publishing. He prints nothing which does not absolutely satisfy his mind both as a whole and in its details.
