Emilie Behrend's piece represents the output of many lesser-known 19th-century composers who contributed to the salon repertoire. It is a straightforward composition focusing on expressive, lyrical phrasing within the lullaby form.
Control of the left-hand arpeggiated figures is essential to ensure they do not overpower the melody.
Comparable difficulty and character — good candidates for what to learn next.
Berceuse is rated Henle level 3 of 9 — late beginner repertoire, roughly ABRSM grades 4–5. In the RCM system it corresponds to about level 3.
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 Berceuse lasts about 2 minutes.
Berceuse is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
