The Well-Tempered Clavier, BWV 846–893, is a collection of two sets of preludes and fugues in all 24 major and minor keys, composed for solo keyboard by Johann Sebastian Bach. In Bach’s time Clavier (keyboard) was a generic name indicating a variety of keyboard instruments, most typically a harpsichord or clavichord – but not excluding an organ either. Modern editions usually refer to both parts as The Well-Tempered Clavier, Book I and The Well-Tempered Clavier, Book II, respectively. The Prelude and Fugue XIII is in F-sharp major. – Maurizio Pollini
