A late-Romantic character piece that reflects the salon music style of the late 19th century. Its distinctiveness lies in its sentimental harmonic progressions and expressive phrasing.
Control the touch to achieve a singing, mournful tone throughout the piece.
Comparable difficulty and character — good candidates for what to learn next.
Andante (Pietà) is rated Henle level 3 of 9 — late beginner repertoire, roughly ABRSM grades 4–5. In the RCM system it corresponds to about level 3.
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.
