Well-Tempered Clavier

The Well-Tempered Clavier is a significant musical work by composer Johann Sebastian Bach, composed in two volumes, completed in 1722 and 1742. Each volume contains a prelude and fugue in every major and minor key, totaling 48 pieces. The term "well-tempered" refers to a tuning system that allows instruments to play in all keys while sounding harmonious. This work showcases Bach's mastery of counterpoint and musical structure and serves both as a teaching tool for musicians and a profound exploration of musical expression. It remains a cornerstone of piano repertoire and Western classical music.
