This piece appears to be a variant title for the previous entry by Albert Wimpfheimer. It retains the same light, charming character suitable for early-intermediate piano students.
At Henle 3 this is a late-beginner piece — comfortable hands-together playing is assumed, and musical shaping starts to matter. The main demands: precise articulation — the difference between crisp and blurred is the piece; fine finger independence within the hand; and Alberti-bass accompaniment kept quiet and even under the melody.
Pay close attention to rhythmic precision during the frequent rhythmic displacements in the middle section.
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.
Dent de Lion 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 Dent de Lion lasts about 2 minutes.
