Autumn II is a brief, atmospheric contemporary solo work by Emil Mern. It is distinctive for its sparse harmonic language and focus on lyrical phrasing.
The primary challenge is maintaining a consistent, delicate cantabile tone throughout the piece.
Comparable difficulty and character — good candidates for what to learn next.
Autumn II is rated Henle level 3 of 9 — late beginner repertoire, roughly ABRSM grades 4–5. In the RCM system it corresponds to about level 4.
You should be comfortable at Henle level 3 — meaning you can already play level 2–3 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 Autumn II lasts about 3 minutes.
Autumn II is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
