Underwater Theme

The "Underwater Theme" is a recurring musical theme composed by Koji Kondo, first heard in World 2-2 of Super Mario Bros. It was originally written in C major with a 3/4 time signature, resembling that of a waltz. As it was "easy to imagine what it should be like," it was the first composition Kondo finished for the game. The theme plays in every level and section set underwater in Super Mario Bros., with following rearrangements largely featuring as title screen music.

Reuses
The following list does not count ports and remakes (such as Super Mario Bros. Deluxe) of Super Mario Bros.

Brawl, where it is split into three distinct sections: The first uses the original theme, the second is an orchestrated arrangement, and the third is a bluegrass arrangement.

Ultimate for any Super Mario-franchise stage.
