The stories surrounding Frédéric Chopin s winter holiday on Mallorca with George Sand in 1838/39 are widely known. It was there in adverse conditions that Chopin completed his Préludes op. 28 which he hadalready begun in Paris. According to George Sand the famous Raindrop Prélude (no. 15) is said to have been composed during a storm on Mallorca; however other sources show that the first sketches were alreadymade in Paris. Our single edition has been taken from the revised edition of the Préludes (HN 882). Detailed information on the genesis of this work and an evaluation of the sources can be downloaded free-of-charge.
