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.
