A contemporary character piece likely influenced by Nordic folk idioms. Its simplicity and clarity make it an accessible miniature for intermediate students.
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; a left hand with real melodic or rhythmic responsibility of its own; and rubato that must breathe naturally without losing the pulse.
Ensure the phrasing is shaped carefully to give the piece a sense of conversational flow.
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.
Duggen is rated Henle level 2 of 9 — beginner repertoire, roughly ABRSM grades 2–3. In the RCM system it corresponds to about level 2.
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 Duggen lasts about 2 minutes.
