This Fanny-Polka by Hammer is a prototypical 19th-century salon dance. It emphasizes rhythmic clarity and simple melodic lines suited for beginner-to-intermediate players.
At Henle 2 this is a beginner-level piece, where steady coordination between the hands is the main hurdle. The main demands: precise articulation — the difference between crisp and blurred is the piece; fine finger independence within the hand; and a left hand with real melodic or rhythmic responsibility of its own.
Focus on the precise rhythmic placement of the 'oom-pah' polka 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.
Fanny-Polka is rated Henle level 2 of 9 — beginner repertoire, roughly ABRSM grades 2–3. In the RCM system it corresponds to about level 3.
You should be comfortable at Henle level 2 — meaning you can already play level 1–2 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 Fanny-Polka lasts about 2 minutes.
