"Down to the Sea" is the first song in the film The Little Mermaid II: Return to the Sea. The song is sung by mainly Ariel and Sebastian, but parts are also sung by Prince Eric, Grimsby, and both humans and merpeople.
The song mainly serves to explain that Ariel is at long last returning to the sea, with her husband and a few subjects, so that both humans and merpeople can celebrate the christening of Ariel and Eric's newborn daughter Melody, the first child ever born of land and sea. At the same time, Ariel is expressing how much she loves her daughter, and that she hopes that Melody will share her love of the sea.
