Das wohltemperierte Klavier, Teil I, Volume I

Das wohltemperierte Klavier, Teil I is a collection of 24 preludes and fugues for keyboard by Johann Sebastian Bach, composed around 1722. The cycle systematically traverses all major and minor keys to explore tempered tuning, demonstrates advanced contrapuntal technique and tonal organisation, and occupies a pivotal position in Bach's output and in the evolution of Western keyboard repertoire.
