Dmitri Dmitriyevich Shostakovich ： 24 Preludes and Fugues No.21 in B-Dur Op.87-21

No. 21, comprising a prelude and a fugue, is distinguished by its clear momentum and the fascination of its counterpoint. The prelude presents changing motion and harmonic shifts with clarity, while the fugue drives the music forward as its subject passes from one voice to another. It is important to differentiate the voices so that each can be heard independently while maintaining the overall flow. Paying attention to the contrast between the prelude’s light forward motion and the fugue’s closely interwoven lines brings the structure’s appeal into sharper focus.
