D major, 4/4 time.

Although it possesses a bright, dance-like character, it is a sophisticated fugue with two counter-subjects, structured as follows: First Exposition (m. 1–) — Interlude 1 (m. 8–) — Second Exposition (m. 10–) — Interlude 2 (m. 12–) — Interlude 3 (m. 14–) — Third Exposition (m. 19–).

In the First Exposition, the subject entry shifts from the upper voice to the lower voice, and two counter-subjects are combined with the subject. In the Third Exposition, contrary to the beginning, the subject entry shifts from the lower voice to the upper voice, and the two counter-subjects are arranged with the subject in a different combination from the First Exposition.

Although the Second Exposition is brief, the upper voice presents the subject in B minor, its parallel key, while the middle voice plays Counter-subject 2 and the lower voice plays Counter-subject 1. This demonstrates a combination pattern that was absent in the First Exposition due to its initial position.
