The Well Tempered Clavier, Book One
Album by Johann Sebastian Bach & Jörg Demus
The Well-Tempered Clavier, Book One is a collection of keyboard preludes and fugues by Johann Sebastian Bach, compiled and first published in 1722. Comprising 24 paired pieces that traverse all major and minor keys under a well‑tempered tuning system, the collection exemplifies Bach's contrapuntal technique and functions as a foundational study in keyboard repertoire and the development of Western tonal harmony.
First released: 1992
