This obscure work is a modest salon composition from the late 19th-century Brazilian piano repertoire. It utilizes simple harmonic structures designed for amateur domestic performance.
At Henle 2 this is a beginner-level piece, where steady coordination between the hands is the main hurdle. The main demands: a true singing tone, with the melody floating above the accompaniment; Alberti-bass accompaniment kept quiet and even under the melody; and precise articulation — the difference between crisp and blurred is the piece.
Focus on evenness of touch in the left hand to support the singing quality of the right hand melody.
Comparable difficulty and character — good candidates for what to learn next.
A level or two down with the same spirit — ideal if this piece is still out of reach.
Where this piece's skills lead: slightly harder works making similar technical demands.
Esmeralda is rated Henle level 2 of 9 — beginner repertoire, roughly ABRSM grades 2–3. In the RCM system it corresponds to about level 2.
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.
A typical performance of Esmeralda lasts about 3 minutes.
