The Toccata movement opens with brilliant passagework. The following sections are loosely separated by double bar lines, comprising four sections in total: a profound, recitative-like Adagio, a bright, dance-like Allegro, and a return to the recitative before the conclusion.

In the subsequent Fugue, strict counterpoint unfolds, employing both the inversion and retrograde forms of the subject. The subject, composed solely of dotted rhythms, is continuous and creates a dense texture with no relaxation. This continues for 190 measures, making this already challenging fugue even more formidable. However, the fugue subject is remarkably clear and possesses a driving force that keeps the listener engaged. This, combined with the contrast to the preceding dance-like section and recitative, results in a highly effective work.
