This salon-style ballade reflects the typical Romantic fascination with nocturnal themes and intimate melodic expression. It is characterized by its vocal-like phrasing and standard ternary structure common to mid-19th-century character pieces.
The primary challenge is maintaining a consistent, singing tone in the right-hand melody against a fluid, broken-chord accompaniment.
