Taken from Bach's Well Tempered Clavier, also known as the 48 Preludes and Fugues, this piece is not unlike the first prelude in construction with arpeggiated chords coming to a free cadenza-like climax towards the end. However this busy little tune is darker in tone and not just because of its minor key. Often (though not always) played as a pair in the order Prelude then Fugue, here is the corresponding Fugue for this Prelude. A must for any serious student of piano, Book 1 and Book 2 are available from Sheet Music Plus.
