The C sharp minor prelude, No. 10, must be the "eagle wings" of Schumann's critique. There is a flash of steel gray, deepening into black, and then the vision vanishes as though some huge bird aloft had plunged down through blazing sunlight, leaving a color-echo in the void as it passed to its quarry. Or, to be less figurative, this prelude is a study in arpeggio, with double notes interspersed, and is too short to make more than a vivid impression.
No. II in B is all too brief. It is vivacious, dolce indeed, and most cleverly constructed. Klindworth gives a more binding character to the first double notes. Another gleam of the Chopin sunshine.
Storm clouds gather in the G sharp minor, the twelfth prelude, so unwittingly imitated by Grieg in his Menuetto of the same key, and in its driving presto we feel the passionate clench of Chopin's hand. It is convulsed with woe, but the intellectual grip, the self-command are never lost in these two pages of perfect writing. The figure is suggestive, and there is a well defined technical problem, as well as a psychical character. Disputed territory is here: the editors do not agree about the twelfth and eleventh bars from the last. According to Breitkopf & Hartel the bass octaves are E both times. Mikuli gives G sharp the first time instead of E; Klindworth, G sharp the second time; Riemann, E, and also Kullak. The G sharp seems more various.
In the thirteenth prelude, F sharp major, here is lovely atmosphere, pure and peaceful. The composer has found mental rest. Exquisitely poised are his pinions for flight, and in the piu lento he wheels significantly and majestically about in the blue. The return to earth is the signal for some strange modulatory tactics. It is an impressive close. Then, almost without pause, the blood begins to boil in this fragile man's veins. His pulse beat increases, and with stifled rage he rushes into the battle. It is the fourteenth prelude in the sinister key of E flat minor, and its heavy, sullen-arched triplets recalls for Niecks the last movement of the B flat minor Sonata; but there is less interrogation in the prelude, less sophistication, and the heat of conflict over it all. There is not a break in the clouds until the beginning of the fifteenth, the familiar prelude in D flat.
This must be George Sand's: "Some of them create such vivid impressions that the shades of dead monks seem to rise and pass before the hearer in solemn and gloomy funereal pomp." The work needs no programme. Its serene beginning, lugubrious interlude, with the dominant pedal never ceasing, a basso ostinato, gives color to Kleczynski's contention that the prelude in B minor is a mere sketch of the idea fully elaborated in No. 15. "The foundation of the picture is the drops of rain falling at regular intervals"—the echo principle again—"which by their continual patter bring the mind to a state of sadness; a melody full of tears is heard through the rush of the rain; then passing to the key of C sharp minor, it rises from the depths of the bass to a prodigious crescendo, indicative of the terror which nature in its deathly aspect excites in the heart of man. Here again the form does not allow the ideas to become too sombre; notwithstanding the melancholy which seizes you, a feeling of tranquil grandeur revives you." To Niecks, the C sharp minor portion affects one as in an oppressive dream: "The re-entrance of the opening D flat, which dispels the dreadful nightmare, comes upon one with the smiling freshness of dear, familiar nature."
The prelude has a nocturnal character. It has become slightly banal from frequent repetition, likewise the C sharp minor study in opus 25. But of its beauty, balance and exceeding chastity there can be no doubt. The architecture is at once Greek and Gothic.
The sixteenth prelude in the relative key of B flat minor is the boldest of the set. Its scale figures, seldom employed by Chopin, boil and glitter, the thematic thread of the idea never being quite submerged. Fascinating, full of perilous acclivities and sudden treacherous descents, this most brilliant of preludes is Chopin in riotous spirits. He plays with the keyboard: it is an avalanche, anon a cascade, then a swift stream, which finally, after mounting to the skies, descends to an abyss. Full of imaginative lift, caprice and stormy dynamics, this prelude is the darling of the virtuoso. Its pregnant introduction is like a madly jutting rock from which the eagle spirit of the composer precipitates itself.
In the twenty-third bar there is curious editorial discrepancy. Klindworth uses an A natural in the first of the four groups of sixteenths, Kullak a B natural; Riemann follows Kullak. Nor is this all. Kullak in the second group, right hand, has an E flat, Klindworth a D natural. Which is correct? Klindworth's texture is more closely chromatic and it sounds better, the chromatic parallelism being more carefully preserved. Yet I fancy that Kullak has tradition on his side.
The seventeenth prelude Niecks finds Mendelssohn-ian. I do not. It is suave, sweet, well developed, yet Chopin to the core, and its harmonic life surprisingly rich and novel. The mood is one of tranquillity. The soul loses itself in early autumnal revery while there is yet splendor on earth and in the skies. Full of tonal contrasts, this highly finished composition is grateful to the touch. The eleven booming A flats on the last page are historical. Klindworth uses a B flat instead of a G at the beginning of the melody. It is logical, but is it Chopin?
The fiery recitatives of No. 18 in F minor are a glimpse of Chopin, muscular and not hectic. In these editions you will find three different groupings of the cadenzas. It is Riemann's opportunity for pedagogic editing, and he does not miss it. In the first long breathed group of twenty-two sixteenth notes he phrases as shown on the following page.
