The famous “Raindrop” Prelude by Polish composer Frederic Chopin. It is the 15th Prelude of a collection of 24 from his Opus 28. According to French writer George Sand, it was conceived during a rainstorm from a morbid daydream in which Chopin saw himself drowned in a lake with heavy drops of icy rain falling rhythmically on his chest. The piece begins serenely and calmly, but turns dark and terrible with rhythmic tapping in the bass notes. It is a very cinematic piece, most recently used in the 2012 Ridley Scott film ‘Prometheus’.
