Kalkbrenner's variation-based fantasy on the famous Mozart duet is a hallmark of his technical school. It demonstrates his reliance on rapid passage work, scales, and finger-independence that was highly regarded in his time.
At Henle 7 this is a late-advanced work — the technical demands are serious and sustained. The main demands: fast passage work that stays light and even at tempo; sweeping arpeggio figures that must stay smooth across positions; and ornaments that need to sound effortless, not squeezed in.
Beyond that, expect fine finger independence within the hand, and a true singing tone, with the melody floating above the accompaniment.
At roughly 10 minutes, stamina and memory become part of the challenge — plan practice in sections.
The rapid-fire fingerwork requires absolute clarity and evenness across the keyboard.
Comparable difficulty and character — good candidates for what to learn next.
A level or two down with the same spirit — ideal if this piece is still out of reach.
Where this piece's skills lead: slightly harder works making similar technical demands.

Fantaisie sur 'La ci darem la mano' (Op.33) is rated Henle level 7 of 9 — late advanced repertoire, roughly ABRSM grade 8 and above. In the RCM system it corresponds to about level 10.
You should be comfortable at Henle level 7 — meaning you can already play level 6–7 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
