This obscure Romantic miniature features a wandering, improvisatory melody over a broken-chord accompaniment. It is distinctive for its use of mid-19th-century salon tropes to create a sense of wistful reverie.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. 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.
The piece requires careful attention to pacing and expressive rubato to prevent the repetitive accompaniment from sounding monotonous.
