Part of a set of six etudes, Op. 42 No. 3 is highly regarded for its beautiful, haunting melody and complex rhythmic layers. It remains one of Arensky's most mature and effective works for the piano.
At Henle 7 this is a late-advanced work — the technical demands are serious and sustained. The main demands: polyrhythms that have to lock together without sounding mechanical; chord voicing — bringing out one note inside a handful of others; and a true singing tone, with the melody floating above the accompaniment.
Beyond that, expect rubato that must breathe naturally without losing the pulse.
Mastering the polyrhythmic interplay between the hands is essential to capturing the piece's character.

Etude Op 42 no 3 is rated Henle level 7 of 9 — late advanced repertoire, roughly ABRSM grade 8 and above. In the RCM system it corresponds to about level 9.
You should be comfortable at Henle level 7 — meaning you can already play level 6–7 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
