🇩🇪Johann Sebastian Bach ： Well-Tempered Clavier I no.4 cis-moll BWV 849

Consisting of a prelude and fugue, this is one of the particularly dense works in Book I of The Well-Tempered Clavier. In the prelude, several voices overlap within a flowing, arpeggio-like texture, creating shifting harmonies and a sustained sense of tension. In the fugue that follows, the subject is passed from one voice to another, and the texture gradually grows richer through imitation and contrapuntal layering. In the prelude, carefully shape the connections between notes and the changing harmonies; in the fugue, keep the subject clear while balancing the volume and articulation of each voice. Avoid rushing, and preserve the flow of every part while sustaining the tension so that the clarity of the structure comes through.
