Henri Bertini, better known for his pedagogical studies, composed this waltz to showcase lyrical phrasing within a dance form. It is characterized by simple, pleasing harmonic progressions typical of the period.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: a waltz lilt that needs charm and a flexible left hand; a true singing tone, with the melody floating above the accompaniment; and careful pedaling — clarity depends on the foot as much as the fingers.
Challenge the student to use a flexible wrist to achieve smooth, connected phrasing in the waltz lines.
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.
Fantaisie-valse (Op.154) is rated Henle level 4 of 9 — intermediate repertoire, roughly ABRSM grades 5–6. In the RCM system it corresponds to about level 5.
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.
