Ernesto Becucci’s 'Ali dorate' ('Golden Wings') is a classic salon waltz typical of the late 19th-century Italian school. It features a sweeping melodic line typical of a lyrical waltz.
Ensure the waltz rhythm is supple and not overly rigid, allowing for natural rubato.
Comparable difficulty and character — good candidates for what to learn next.
Ali dorate is rated Henle level 4 of 9 — intermediate repertoire, roughly ABRSM grades 5–6. In the RCM system it corresponds to about level 5.
You should be comfortable at Henle level 4 — meaning you can already play level 3–4 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 Ali dorate lasts about 4 minutes.
Ali dorate is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
