A work by Finnish composer Heikki Suolahti that blends late-Romantic lyricism with early 20th-century harmonic sensibilities. It is an expressive piece centered on melodic development and atmosphere.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: sweeping arpeggio figures that must stay smooth across positions; rubato that must breathe naturally without losing the pulse; and careful pedaling — clarity depends on the foot as much as the fingers.
Beyond that, expect a true singing tone, with the melody floating above the accompaniment.
Balancing the lush melodic lines with the rhythmic fluidity required for an impromptu is the core challenge.
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.
Fantasia impromptu (Op.9) is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7. In the RCM system it corresponds to about level 7.
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.
