Philipp Lamoury was a late 19th-century composer whose works are firmly rooted in the tradition of piano salon music. This Berceuse features a traditional, warm harmonic progression typical of the period.
Pay close attention to smooth, connected pedaling to bridge the gaps between the harmonic changes.
Comparable difficulty and character — good candidates for what to learn next.

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.
