This is an alternate transliteration entry for the same piece by Aleksey Stanchinsky. It features the same sophisticated harmonic language and contrapuntal complexity typical of his early 20th-century Russian output.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: fine finger independence within the hand; polyrhythms that have to lock together without sounding mechanical; and rubato that must breathe naturally without losing the pulse.
Beyond that, expect chord voicing — bringing out one note inside a handful of others.
Focus on the independence of the left hand to support the nuanced phrasing of the melody.
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.
Etude for Piano is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7. In the RCM system it corresponds to about level 8.
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.
A typical performance of Etude for Piano lasts about 3 minutes.
