Dedicated to the Queen of Romania, this piece is an example of the grander style of commemorative salon music. It features more ambitious textures than typical teaching pieces.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: octave passages that demand a relaxed wrist to avoid tension; wide stretches that reward larger hands and clever redistribution; and chord voicing — bringing out one note inside a handful of others.
The wide-span chords require careful rotation of the wrist to ensure tonal evenness.
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.
Where this piece's skills lead: slightly harder works making similar technical demands.
Elisabeth de Roumanie (Op.882) is rated Henle level 4 of 9 — intermediate repertoire, roughly ABRSM grades 5–6. In the RCM system it corresponds to about level 4.
You should be comfortable at Henle level 4 — meaning you can already play level 3–4 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
