Bach's Chromatic Fantasia and Fugue pushed boundaries with unprecedented harmonic exploration, using daring chromaticism to create dramatic tension. The fantasia's improvisatory style mimics vocal recitatives, while the fugue builds its entire structure around a chromatically ascending subject – a radical technique for its time.
This Baroque masterpiece showcases Bach's harmonic daring through dramatic chromatic passages in the Fantasia, contrasted with a rigorously structured Fugue. Its innovative keyboard techniques expanded the expressive possibilities of the harpsichord.
