El as de oros is a characteristic salon waltz by the Spanish composer Antonio Curbella. It features the rhythmic lilt and melodic grace associated with Spanish parlor music of the late 19th century.
At Henle 3 this is a late-beginner piece — comfortable hands-together playing is assumed, and musical shaping starts to matter. The main demands: a waltz lilt that needs charm and a flexible left hand; a true singing tone, with the melody floating above the accompaniment; and careful pedaling — clarity depends on the foot as much as the fingers.
Ensure the first beat of the waltz is grounded without becoming overly heavy.
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.
El as de oros 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 El as de oros lasts about 3 minutes.
