This Berceuse by Maurice Deffrennes is a short, lyrical piece designed to showcase the singing qualities of the piano. Its simplicity and charm are hallmarks of the amateur piano literature of the era.
The student must ensure the legato articulation remains unbroken throughout the lyrical melodic phrases.
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 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 Berceuse lasts about 3 minutes.
