This is a Neapolitan-style character piece rooted in the tradition of Italian song transcriptions for piano. Its distinctiveness lies in the vocal-like quality of the melody, which requires a heavy emphasis on tone production.
The student must learn to sustain long, vocal-like melodic lines without allowing the accompaniment to overpower the texture.
Comparable difficulty and character — good candidates for what to learn next.
