Julius Isserlis, known for his late Romantic sensibilities, composed this Fairy Tale with a focus on melodic warmth. It is distinguished by its Russian-influenced lyricism and subtle harmonic shifts.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: rubato that must breathe naturally without losing the pulse; a true singing tone, with the melody floating above the accompaniment; and a left hand with real melodic or rhythmic responsibility of its own.
Focus on balancing the middle-voice accompaniment against the main melodic line.
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.
Fairy Tale (Op.6) is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7. In the RCM system it corresponds to about level 5.
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.
