Who is the author of “The Well-Tempered Clavier,” an influential collection of preludes and fugues?

Johann Sebastian Bach

Johann Sebastian Bach, a cornerstone of Baroque music, composed "The Well-Tempered Clavier," a set of two books each containing 24 preludes and fugues in all major and minor keys. This monumental work was designed not only as a technical feat, demonstrating the viability of playing in all keys through equal temperament, but also as a collection of extraordinary beauty and expressiveness. "The Well-Tempered Clavier" has influenced countless composers after Bach, including Mozart, Beethoven, and Chopin.
