William Conrad Polla composed numerous light piano works intended for social enjoyment. The piece is distinguished by its clean, dance-like structure and approachable melodic contours.
At Henle 3 this is a late-beginner piece — comfortable hands-together playing is assumed, and musical shaping starts to matter. The main demands: a left hand with real melodic or rhythmic responsibility of its own; sweeping arpeggio figures that must stay smooth across positions; and precise articulation — the difference between crisp and blurred is the piece.
Beyond that, expect chord voicing — bringing out one note inside a handful of others.
Ensure that the melody in the right hand is projected clearly above the arpeggiated left-hand accompaniment.
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.
Curly is rated Henle level 3 of 9 — late beginner repertoire, roughly ABRSM grades 4–5. In the RCM system it corresponds to about level 3.
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 Curly lasts about 3 minutes.
