🇩🇪Johann Sebastian Bach ： Well-Tempered Clavier I no.19 A-Dur BWV 864

This pairing of prelude and fugue forms No. 19 of Book I of the Well-Tempered Clavier. The prelude is marked by light, flowing motion and clear rhythmic energy; it is important to preserve the direction of each phrase while allowing the pulse to move naturally. In the fugue, the subject is passed from voice to voice, and the overlapping contrapuntal lines shape the music. Bring out the subject while maintaining the independence of each voice, and use clear articulation with moderate pedal to preserve transparency without making the texture too hard-edged. This also highlights the contrast between the prelude and fugue.
