This is a light, salon-style composition that emphasizes melody and simple, evocative harmony. Its style is typical of early 20th-century American parlor music, often found in pedagogical collections of the era.
Pay close attention to the balance between the melodic top voice and the harmonic accompaniment.
Comparable difficulty and character — good candidates for what to learn next.
Alhambra 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 Alhambra lasts about 3 minutes.
Alhambra is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
