Inspired by Bach's Well-Tempered Clavier, Chopin wrote a set of 24 preludes for piano each in a different major or minor key. From a pianist's perspective this prelude in B minor is the inverse of the famous prelude No.4 in E minor, because the left hand plays a melody while the right hand plays repeated notes or chords. However the melody is more expressive with a much wider range. This is the original version for piano, though we also have an arrangement of this prelude for Woodwind Quartet. The complete set of piano preludes by Chopin is available from Sheet Music Plus (US) or The Music Room (UK).
