This fantasy by Louis Couperin showcases the composer's mastery of the stylus phantasticus. It features intricate polyphonic textures and daring harmonic progressions that were ahead of their time.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: independent voices that must each sing on their own line; ornaments that need to sound effortless, not squeezed in; and fine finger independence within the hand.
Beyond that, expect precise articulation — the difference between crisp and blurred is the piece.
The primary challenge is voicing the individual lines clearly while maintaining the stylistic demands of Baroque ornamentation.
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 is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7. In the RCM system it corresponds to about level 6.
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.
