Marco Anzoletti's work is a violin-inflected piano miniature that emphasizes vocal lines. It is notable for its intricate ornamentation and late-Romantic sensibilities.
Mastering the subtle ornamentation while maintaining a seamless, singing tone is the main technical task.
Comparable difficulty and character — good candidates for what to learn next.
Cantilena is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7. In the RCM system it corresponds to about level 6.
You should be comfortable at Henle level 5 — meaning you can already play level 4–5 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 Cantilena lasts about 4 minutes.
Cantilena is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
