J.S. Bach's "The Well-Tempered Clavier"

J.S. Bach's "The Well-Tempered Clavier" is a collection of 48 keyboard pieces, divided into two volumes, each containing a prelude and fugue in every major and minor key. Composed in the early 18th century, it showcases Bach's mastery of counterpoint and musical structure. The "well-tempered" tuning system allows instruments to play in all keys, making it versatile and innovative.
