This is a sentimental salon-style piece composed by Nicholas Ruaimi in a late Romantic idiom. It is characterized by its song-like melody and modest harmonic language, typical of amateur-focused music from the early 20th century.
At Henle 3 this is a late-beginner piece — comfortable hands-together playing is assumed, and musical shaping starts to matter. The main demands: a true singing tone, with the melody floating above the accompaniment; rubato that must breathe naturally without losing the pulse; and careful pedaling — clarity depends on the foot as much as the fingers.
Beyond that, expect chord voicing — bringing out one note inside a handful of others.
Focus on balancing the melody over the accompaniment while maintaining a consistent lyrical tone.

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.
