"Lullaby" is a simple song of reassurance, as a mother may sing to her child to stave off a fear of the darkness and solitude of night. The beauty of this text lies in its dual nature, as it also serves to comfort those who grieve over loss. The line "the day is done, and gone the sun" has its origins in the first line of the text traditionally sung to "Taps," the tune generally played on bugle or trumpet for military funerals or to signal the end of the day. The power of this piece lies in its simplicity.
