This Fantasia is an expressive keyboard work by J.S. Bach that balances fugal intensity with improvisatory-style passagework. It stands out for its structural density and the sophisticated counterpoint characteristic of Bach's keyboard maturity.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: independent voices that must each sing on their own line; ornaments that need to sound effortless, not squeezed in; and fine finger independence within the hand.
Beyond that, expect precise articulation — the difference between crisp and blurred is the piece, and continuous sixteenth-note figuration that must ripple, not chatter.
The primary challenge is maintaining clarity and consistent articulation throughout the dense contrapuntal textures.
