Marpurg's fugue in D major, written for two voices, is an up tempo, spiritied composition. "Fugue" is probably not the most accurate description of this piece. The fugue theme appear a few times at the beginning of the composition. The rest of it is build on various motifs derived from the fugue theme. Actually a clever way of writing. It makes you constantly think that the fugue theme is being played, well in fact it is not.
