A complex work combining improvisatory fantasia elements with a strict fugue. It represents Bach's late-Baroque style, blending technical difficulty with dense, rigorous contrapuntal development.
At Henle 6 this is an advanced piece that assumes fluent technique and rewards mature interpretation. The main demands: independent voices that must each sing on their own line; fine finger independence within the hand; and ornaments that need to sound effortless, not squeezed in.
Beyond that, expect precise articulation — the difference between crisp and blurred is the piece, and chord voicing — bringing out one note inside a handful of others.
At roughly 8 minutes, stamina and memory become part of the challenge — plan practice in sections.
Achieve absolute independence of voices throughout the fugal sections while maintaining a consistent pulse.
