This is a rare 18th-century keyboard work featuring descriptive bird-call imitations typical of the rococo style. It is distinctive for its use of period-specific ornamentation to evoke the 'Uccellaja' or bird sanctuary.
At Henle 3 this is a late-beginner piece — comfortable hands-together playing is assumed, and musical shaping starts to matter. The main demands: ornaments that need to sound effortless, not squeezed in; Alberti-bass accompaniment kept quiet and even under the melody; and precise articulation — the difference between crisp and blurred is the piece.
The primary challenge is executing the light, decorative ornaments with clarity and rhythmic precision.
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.
Divertimento per Cembalo in cui si esprime una Uccellaja 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.
