La la la... la." A little girl stands alone and sings, but hears no response. Gathering her courage and her curiosity, she skips farther out into the world, singing away to the trees and the pond and the reeds -- but no song comes back to her. Day passes into night, and the girl dares to venture into the darkness toward the light of the moon, becoming more insistent in her singing, climbing as high as she can, but still there is silence in return. Dejected, she falls asleep on the ground, only to be awakened by an amazing sound... She has been heard. At last.
