Lullaby began as a vocal work based on a poem of the same name by Horace Smith. Much as a lullaby is sung at twilight, a time is not quite day yet not quite night, this piece exists in, and shifts between, D major and B minor. The melody, in the treble of the secondo part, should be performed sweetly and naturally with rubato, as a parent would sing to a newborn child.
