Francisco Cimadevilla was a Spanish composer who wrote many works for guitar and piano in a light, melodic style. Caramelo is a charming, sweet character piece that highlights a singing melody against a simple, broken-chord accompaniment.
Focus on balancing the melody in the right hand against the softer accompaniment figures.
Comparable difficulty and character — good candidates for what to learn next.
Caramelo 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 Caramelo lasts about 3 minutes.
Caramelo is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
Pieces at a comparable difficulty and character include Black Beauty by Duke Ellington, Berceuse by Rudolf Friml, Albumblatt by Moritz Moszkowski — see the full similar-pieces list on this page.
