The Sea Tangle, or The Sisters

Two sisters sit out on a reef, reflecting on their childhood. They love the same man, yet he has chosen the younger sister for his bride. The jealous older sister lulls the younger sister to sleep with a song, braiding her hair with the seaweed that grows on the rock so that she is trapped as the tide comes in.

The jealous sister eventually marries her widowed brother-in-law. Meanwhile, a bard finds some bones on the shore and turns them into a harp. As he plays at their wedding feast, the bones of the drowned sister cry out through the harp and tell her story. This song is what I imagine the wedding guests might have heard.
