About this work

Oddly, the prelude in this pair is itself almost a fugue; its minuet-like opening theme makes a second entrance and begins a contrapuntal dialog with itself. Two further themes, so closely related as to barely count as separate motifs, arrive and receive similar treatment, with all this happening at a moderate tempo in less than a minute and a half. The fugue is also something of a novelty, in the unusual 9/18 meter. Its playful, peekaboo theme launches a three-voice structure, entering from the top of the keyboard down.
