This is a sentimental parlor piece by Frank Peabody Atherton, typical of early 20th-century salon music. It relies heavily on melodic shaping and expressive phrasing within a predictable harmonic structure.
The primary challenge is maintaining a singing tone while balancing the inner harmonic accompaniment.
Comparable difficulty and character — good candidates for what to learn next.
Camaraderie (Op.213) 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.
A typical performance of Camaraderie (Op.213) lasts about 3 minutes.
