Published in 1788 alongside Hob.XVI: 44 and 45. The exact composition date is uncertain, but stylistically, it is considered to be from the same period as Hob.XVI: 45 (1766) or around 1770.

All themes are bright and clear, and the work as a whole possesses an unconstrained atmosphere. On the other hand, in the anxious, sometimes intense minor sections that frequently appear in the development, one can glimpse the expressive characteristics of excitement and passion typical of Haydn's works from the late 1760s to the early 1770s. Furthermore, it encompasses several unexpected elements, demonstrating its depth: tonalities with four key signatures (rare for this period, with even more key signatures in the second movement in the subdominant key), frequent use of fermatas, pauses created by rests, and somewhat abrupt modulations.

First Movement: Allegro moderato, A-flat major, 4/4 time. Sonata form.

Although a somewhat large-scale movement, it is given contrast and emphasis by fermatas that provide appropriate transitions and by passages with a toccata-like momentum.

Second Movement: Adagio, D-flat major, 3/4 time. Sonata form.

Although in sonata form, the recapitulation is closely intertwined with the development section; while it returns to the tonic key, it progresses more developmentally than as a mere restatement. The first theme possesses a calm elegance, reminiscent of a sarabande found in Baroque dance suites.

Third Movement: Finale. Presto, A-flat major, 2/4 time. Sonata form.

A fast movement befitting a finale. Both themes feature intricate sixteenth-note movements, maintaining their momentum until the very end.
