José María Arguedas: Realidad y Mito - El Arpa (1977)
A harpist (Pedro Llana) is seen positioning his harp near a waterfall. The narrator's voice says, "We knew that harpists went to the mountains to learn new melodies from the waterfalls." The harpist falls asleep, and some children climb up to steal his harp. The harpist wakes up and throws them off.
