This four-voice fugue from The Well-Tempered Clavier Book II showcases Bach's mastery of counterpoint through intricate subject transformations and stretto techniques, exploiting the unusual key's harmonic possibilities.
Prelude and Fugue in C-sharp minor, BWV 873, is a pair of keyboard compositions from the second book of J.S. Bach's seminal work, The Well-Tempered Clavier. The prelude is a flowing, two-part invention-like texture, while the fugue is a sophisticated three-voice construction showcasing Bach's mastery of counterpoint in a key that was considered remote and expressive in the Baroque era.
