This Allegro is a typical pedagogical sonata-form movement from the Classical era. It is characterized by clear textures and the use of the ubiquitous Alberti bass common in Hummel's earlier teaching works.
The primary challenge is maintaining an even, light articulation in the left hand while projecting the melodic clarity in the right.
Comparable difficulty and character — good candidates for what to learn next.
Allegro is rated Henle level 3 of 9 — late beginner repertoire, roughly ABRSM grades 4–5. In the RCM system it corresponds to about level 4.
You should be comfortable at Henle level 3 — meaning you can already play level 2–3 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
A typical performance of Allegro lasts about 2 minutes.
Allegro is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
