Under the Sea originated in Disney’s 1989 animated film The Little Mermaid. Written by composer Alan Menken and lyricist Howard Ashman, it is performed in the film by Sebastian, voiced by Samuel E. Wright. The song won the Academy Award for Best Original Song and became one of the film’s defining musical numbers. Short excerpts remain common in online edits because the melody quickly signals oceans, sea life, tropical fun, and the humorous idea that life underwater is better than life on land.
