Inspired by Bach's Well-Tempered Clavier, Chopin wrote a set of 24 preludes for piano each in a different major or minor key. This prelude in E minor features a slow melancholy melody in the right hand over repeated quaver chords in the left hand with a descending feel which seems to give the impression of fading away. This is one of Chopin's most famous preludes: it has featured in many film and television soundtracks and Chopin requested the work to be played at his own funeral. The complete set of piano preludes by Chopin is available from Sheet Music Plus (US) or The Music Room (UK).
