Part of the wider set of unmeasured works, this Fantaisie highlights Couperin's mastery of the stylus phantasticus adapted for the keyboard. Its beauty lies in the sudden shifts of harmonic color and registral changes.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: independent voices that must each sing on their own line; ornaments that need to sound effortless, not squeezed in; and precise articulation — the difference between crisp and blurred is the piece.
Beyond that, expect fine finger independence within the hand.
Achieving a natural, vocal-like phrasing despite the lack of structural time signatures is essential.
