History
The Netherlands Bach Society connects this Prelude's two-part exchanges with Bach's C-major Invention, BWV 772. Running figures and accompaniment trade roles, making teaching through musical dialogue part of its reference interpretation. This comparison concerns the individual Prelude, not its paired Fugue.

What to listen for
A compact cell reverses its roles
A small upper cell receives a slower lower reply, then moves below a slower upper answer. Hear the same kind of figure in a different layer.
Interlocking figures expand the first section
Cross-staff lower figures join upper sequences and short cadential replies. Follow their continuity through the notation changes.
A more insistent second entry
Repeated upper-note figures and ornamented responses start the second repeated region. Hear their contrast with the compact opening cell.
An inner reply meets a held upper strand
A longer upper sound overlaps an active inner response near the close. Hear both layers settle into the final C-minor chord.
How to practise it
Staggered start and recurring paired arrivals; longer low pattern with quicker high movement.
- Practise the staggered opening as one continuous pulse, hearing the single attacks between the fuller arrival points rather than inserting pauses.
- Keep the low pattern at its longer spacing while the high pitches move twice as often, and make the returning low pitch a fresh attack rather than an unintended tie.
How hard is it
Rhythmic interplay and contrapuntal movement require coordinated articulation and independent phrase direction.
