This piece is a rarely performed nocturne-style fantasy by the Spanish composer Vicente Costa Nogueras. It is distinct for its mid-Romantic Spanish salon style, blending lyrical melodies with improvisatory decorative flourishes.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: a true singing tone, with the melody floating above the accompaniment; rubato that must breathe naturally without losing the pulse; and careful pedaling — clarity depends on the foot as much as the fingers.
Beyond that, expect chord voicing — bringing out one note inside a handful of others.
The primary challenge lies in balancing the singing melody against the intricate, sweeping accompanimental figures.
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.

Fantasia Nocturno is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7. In the RCM system it corresponds to about level 7.
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.
