Anton Rubinstein's Op. 77 Fantaisie is a virtuosic work typical of the composer's high Romantic output. It is characterized by stormy, orchestral-like writing that demands immense technical facility and stamina.
At Henle 7 this is a late-advanced work — the technical demands are serious and sustained. The main demands: fast passage work that stays light and even at tempo; sweeping arpeggio figures that must stay smooth across positions; and sharp dynamic and character contrasts held together in one arc.
Beyond that, expect octave passages that demand a relaxed wrist to avoid tension, and chord voicing — bringing out one note inside a handful of others.
At roughly 8 minutes, stamina and memory become part of the challenge — plan practice in sections.
The primary challenge is maintaining clarity and structural control during the heavy, rapid passagework.
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 (Op.77) is rated Henle level 7 of 9 — late advanced repertoire, roughly ABRSM grade 8 and above. In the RCM system it corresponds to about level 10.
You should be comfortable at Henle level 7 — meaning you can already play level 6–7 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 Fantaisie (Op.77) lasts about 8 minutes.
