Known primarily for his flute works, Terschak's piano writing is virtuosic and light. This piece mimics bird calls through rapid passagework and delicate, high-register ornamentation.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: fast passage work that stays light and even at tempo; 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.
Ensure the ornamentation is precise and articulated with lightness to imitate the naturalistic subject matter.
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.
Die Nachtigall (Op.135) 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.
