Tchaikovsky's Opus 39 is a great set of short pieces for early to late intermediate pianists. Tchaikovsky sub-titled this collection "24 easy pieces (à la Schumann)". Like his predecessor, Tchaikovsky had the innate ability to write for young people, as illustrated here with this set of charming and characteristic miniatures. "Old French song" has a melancholic character. The main challenge here is to voice the music properly, creating good melodic lines.
