Two sisters, Uma and Purnima, were lost in the jungle.
A tiger attacked; he devoured Uma, but Purnima escaped. A man later rescued her, and they married.
A bamboo grove grew from Uma's bones, and shepherds made flutes from the bamboo. When the shepherds played these flutes, a mysterious woman would emerge; she sang sadly and cooked and cleaned for them, and then disappeared back into the flute.
"That must be my sister!" exclaimed Purnima. She waited at a shepherd's house, and when Uma emerged from the flute, they embraced, and Uma did not go back into the flute again.
Inspired by: "Two Sisters," in Folktales from India, by A. K. Ramanujan, who heard the story from Sitakant Mahapatra.
Notes: You can read about the Santal people of India, Bangladesh and Nepal at Wikipedia. The original version of this story is much more elaborate, and it contains the words of the song that the dying and then dead woman sings. I added the names to make the story easier to tell. Similar legends of "singing bones" are found all over the world.
