How is Lullaby and example of storytelling?

In all of her work, Silko is interested in representing the storytelling style of the Native American oral tradition in the form of written English. Silko's narrative style of interweaving the old woman's memories of the past with her present circumstances creates a non-linear narrative, in which thoughts and memories circle back on one another. Silko also represents elements of the oral tradition in the story's ending; when she perceives that her husband Chato, lying curled up in the snow, is dying, Ayah sings a lullaby that her grandmother used to sing to her. This is an important element of the story, because Silko is particularly interested in the ways in which the oral tradition is passed on from grandmother to granddaughter.
