This piece utilizes light, flowing sixteenth-note patterns to evoke the sensation of soft murmurs. It is characteristic of the late-Romantic salon style, focusing on color and delicate ornamentation.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: continuous sixteenth-note figuration that must ripple, not chatter; a true singing tone, with the melody floating above the accompaniment; and chord voicing — bringing out one note inside a handful of others.
Use a light, even touch to ensure the sixteenth notes do not overpower the lyrical melody.
