A graceful and charming waltz, characteristic of the late Romantic era, balancing melodic elegance with rhythmic lilt. It likely features a flowing melody over a supportive harmonic accompaniment.
Maintaining a consistent and graceful waltz rhythm while allowing for expressive rubato in the melodic line is important.
2ème Valse is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7. In the RCM system it corresponds to about level 7.
You should be comfortable at Henle level 5 — meaning you can already play level 4–5 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 2ème Valse lasts about 4 minutes.
