Cruel Sister is a stirring and fantastic Old English ballad. The tale is of two sisers — one bright as the sun, and the other cold and dark. One day, so that she can have the love of a young man who has come courting, the dark sister pushes the bright sister into the sea. Two minstrels find the dead sister washed up on the shore and shape her breastbone into a fine harp strung with her yellow hair. They come to play at the cold dark sister's wedding. As the sound of the harp reaches the bride's ears, the ballad concludes "and surely now her tears will flow." While my piece references no words and quotes no music from the original tune, it does follow the dramatic arc of the ballad — the music reflecting an argument that builds, a body floating on the sea, the mad harp.
