A short, modern character piece designed to explore coloristic intervals. It uses simple modal harmonies to create an impressionistic atmosphere.
The student must work on maintaining evenness in the articulation across both hands during sustained tone passages.
Comparable difficulty and character — good candidates for what to learn next.

You should be comfortable at Henle level 2 — meaning you can already play level 1–2 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
