This part of Hummel's is from the Etude in A Minor, which is the concluding movement of the composer's Piano Sonata No. 3 in F Minor. It is composed in a ternary form, with three distinct sections. The first section, marked Allegretto, follows a sonatina-like structure of two related themes, each repeated twice in a contrasting manner. The middle section, marked Dolce, presents a beautiful, lyrical melody which is later repeated in the third section. The fast and energetic third section, marked Presto, provides a thrilling conclusion to the movement.
