J.S. Bach - The Well-Tempered Clavier, Book 1: Preludes and Fugues (performed by Sviatoslav Richter)

The Well-Tempered Clavier, BWV 846–893, is two sets of preludes and fugues in all 24 major and minor keys for keyboard by Johann Sebastian Bach. In the composer’s time clavier, meaning keyboard, referred to a variety of instruments, most typically the harpsichord or clavichord but not excluding the organ. The modern German spelling for the collection is Das wohltemperierte Klavier (WTK; German pronunciation: [das ˌvoːlˌtɛmpəˈʁiːɐ̯tə klaˈviːɐ̯]). Bach gave the title Das Wohltemperirte Clavier to a book of preludes and fugues in all 24 keys, major and minor, dated 1722, composed “for the profit and use of musical youth desirous of learning, and especially for the pastime of those already skilled in this study“. Some 20 years later Bach compiled a second book of the same kind, which became known as The Well-Tempered Clavier, Part Two (in German: Zweyter Theil, modern spelling: Zweiter Teil).
