Prelude Op.28 No.15 in D-Flat Major "Raindrop" by Frederic Chopin (1810-1849) by Johnson Nicholas Zhang published on 2012/11/11 05:18:48 +0000 The Prelude Op. 28, No. 15, by Frédéric Chopin, known as the "Raindrop" prelude, is one of the 24 Chopin preludes. Usually lasting between five and seven minutes, this is the longest of the preludes. The prelude is noted for its repeating A-flat, which appears throughout the piece and sounds like raindrops to many listeners The prelude opens with a "serene" theme in D flat. It then changes to a "lugubrious interlude" in C sharp minor, "with the dominant pedal never ceasing, a basso ostinato".The repeating A flat, which has been heard throughout the first section, here becomes more insistent. Following this, the prelude ends with a repetition of the original theme. Niecks says, "This C sharp minor portion...affects one like an oppressive dream; the re-entrance of the opening D flat major, which dispels the dreadful nightmare, comes upon one with the smiling freshness of dear, familiar nature – only after these horrors of the imagination can its serene beauty be fully appreciated.
