Robert Fischhof’s Ballet mignon is a charming salon-style piece characteristic of the late 19th-century parlor repertoire. It is distinguished by its light, dance-like melody and graceful, uncomplicated structure.
The primary challenge is maintaining a light, balletic touch while ensuring the melodic phrasing remains distinct from the accompaniment.
Comparable difficulty and character — good candidates for what to learn next.
Ballet mignon is rated Henle level 4 of 9 — intermediate repertoire, roughly ABRSM grades 5–6. In the RCM system it corresponds to about level 6.
You should be comfortable at Henle level 4 — meaning you can already play level 3–4 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
