Robert Henriques' Op. 4 Albumblatt is a charming, lightweight character piece suited for intermediate study. It utilizes standard Romantic harmonic progressions to evoke a sense of salon-style intimacy.
The primary challenge is balancing the waltz-rhythm accompaniment against the melodic foreground.
Comparable difficulty and character — good candidates for what to learn next.
Albumblatt (Op. 4) 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.
