A work by the Polish virtuoso Józef Wieniawski that combines a brooding, romantic fantasy structure with a rigorous fugal development. It bridges the gap between traditional contrapuntal forms and late-Romantic piano textures.
At Henle 7 this is a late-advanced work — the technical demands are serious and sustained. The main demands: independent voices that must each sing on their own line; fine finger independence within the hand; and sharp dynamic and character contrasts held together in one arc.
Beyond that, expect chord voicing — bringing out one note inside a handful of others, and several simultaneous layers, each needing its own dynamic level.
At roughly 9 minutes, stamina and memory become part of the challenge — plan practice in sections.
The main difficulty lies in balancing the complex, dense polyphonic lines during the fugue while maintaining a coherent dramatic arc.
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.
Lesser-known works by the same hand, at a comparable level.
Fantaisie et Fugue (Op.25) 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 9.
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.
