A 19th-century salon polka based on melodies from Verdi's opera, arranged for the home performer. It is a lighthearted example of the era's obsession with operatic transcription.
At Henle 2 this is a beginner-level piece, where steady coordination between the hands is the main hurdle. The main demands: Alberti-bass accompaniment kept quiet and even under the melody; precise articulation — the difference between crisp and blurred is the piece; and a waltz lilt that needs charm and a flexible left hand.
Keep the light, dance-like pulse consistent while managing the simple left-hand accompaniment patterns.
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.
Ernani Polka is rated Henle level 2 of 9 — beginner repertoire, roughly ABRSM grades 2–3. In the RCM system it corresponds to about level 3.
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 Ernani Polka lasts about 2 minutes.
