The myth, as it's usually told
When Eurydice died of a snakebite, Orpheus walked into the underworld and sang until Hades and Persephone agreed to let her go. There was one condition: he must not look back at her until they had both reached the upper world. At the very edge of the light he turned around, and she was gone.
What the song hears
The most famous mistake in myth, sung from inside the moment he turned around.
