This work represents the transition from the late Classical style to early Romantic expressivity. It features structural experimentation by combining the improvisatory nature of a fantasy with the rigorous form of a sonata.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: Alberti-bass accompaniment kept quiet and even under the melody; precise articulation — the difference between crisp and blurred is the piece; and fine finger independence within the hand.
Beyond that, expect a true singing tone, with the melody floating above the accompaniment.
At roughly 8 minutes, stamina and memory become part of the challenge — plan practice in sections.
The primary challenge is maintaining structural clarity while executing the frequent shifts in thematic material.

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.
