Underground Theme

The "Underground Theme" is a recurring musical theme in the Mario franchise composed by Koji Kondo, first heard in underground areas in Super Mario Bros. The original theme is a short, looping tune played in 3/4 time and lasting approximately 11 seconds long, and it plays in every underground level in the game. In composing the theme, Kondo said, "It was really concentrated on the space between the notes, and using a few notes to create that feeling of being underground -- that sort of creepy atmosphere is something I really focused on." Super Mario Bros. designer Shigeru Miyamoto has stated that the theme was an "even more perfect fit" than the Ground Theme. Like the Ground Theme, the Underground Theme has seen many reuses and arrangements in later Mario games and media.

The theme shares a similar melody with the instrumental "Let's Not Talk About It" from 's second Friendship album, released in 1979.

Super Mario Bros. Special
In Super Mario Bros. Special, the Underground Theme plays in underground levels at a slower tempo than the original similar to the Ground Theme.

Super Mario Bros. 3
In Super Mario Bros. 3, an arrangement of the Underground Theme plays in underground areas and bonus rooms. It also plays in the main levels of Dark Land; the game's Ground Theme is completely absent from that world. This version is the first to use a 4/4 time signature and add a percussion beat at the start of the theme (which carries through the rest of the theme), both traits which would go on to be reused in many of the later arrangements.

This version is reused in Super Mario Maker and Super Mario Maker 2 in Super Mario Bros. 3-styled Underground levels, as well as in Paper Mario: Color Splash in the Super Mario Bros. 3 portion of Green Energy Plant, though it is given an echo effect if Mario flips into 3D.

Super Mario All-Stars
For the respective underground levels in Super Mario All-Stars, rather than both the original and Super Mario Bros. 3 versions receiving 16-bit arrangements, a single arrangement of the latter is instead used for Super Mario Bros., Super Mario Bros.: The Lost Levels and Super Mario Bros. 3.

Super Mario 64
In Super Mario 64, an extended arrangement plays in cave areas, including Hazy Maze Cave, Wet-Dry World, Wiggler's cave of Tiny-Huge Island, Behind the Waterfall, the pyramid in Shifting Sand Land, and the igloo in Snowman's Land. New notes were added in this arrangement, and the introduction is a longer, unique melody. The theme's main melody is played on bass guitar.

In Super Mario 64 DS, this arrangement returns in all areas in which it was present in the original game, and is also used in Goomboss Battle.

Super Mario Advance
In the Mario Bros. remake featured in Super Mario Advance, a fast-paced arrangement appears as one of the two regular stage themes, first playing in Phase 5. The arrangement uses the NES bass sound for the main melody. The Mario Bros. remake and its arranged music return in all three of the later Super Mario Advance games.

Super Mario Sunshine
Multiple arrangements are featured in Super Mario Sunshine. The first is heard on Delfino Airstrip when Mario first arrives, played on strings and piano. A techno arrangement plays when Mario chases down Shadow Mario. The first six notes played on an electric guitar can be heard when Shadow Mario reveals his face during the cutscene where the Grand Pianta Statue appears. Another arrangement plays when using manholes.

The main melody is again played on bass guitar.

New Super Mario Bros.

A chiptune version of the Underground Theme can also be heard approximately three minutes into the credits music.

In Super Mario Galaxy, three arrangements were arranged by the game's main composer Mahito Yokota. The first, titled "Space Athletic" in the game's original soundtrack, is a slower-paced, techno arrangement that plays on several galaxies and planets, including Flipswitch Galaxy, Sand Spiral Galaxy, and the interiors of Battlerock Galaxy, Dusty Dune Galaxy's pyramid, and Dreadnought Galaxy.

The second, officially titled "Interlude", is a much slower-paced, eerie arrangement that plays in areas such as the first area of Ghostly Galaxy and Deep Dark Galaxy, as well as before the boss fight with Dino Piranha and Fiery Dino Piranha after breaking their eggs. This version only uses the theme's first four measures.

The third, titled "Cosmic Comet", is a fast-paced techno arrangement that mixes in the Ground Theme from Super Mario Bros. and Shadow Mario's theme from Super Mario Sunshine. The Underground Theme is used as the bassline for the song, which plays in Cosmic Comet and Fast-Foe Comet missions.

New Super Mario Bros. Wii
Another arrangement based on Super Mario Bros. 3s version plays in underground levels in New Super Mario Bros. Wii, which also resembles New Super Mario Bros.s version, incorporating vocals. Additional percussion can be heard if a player is riding Yoshi. This arrangement is reused in New Super Mario Bros. 2, New Super Mario Bros. U, New Super Luigi U, Puzzle & Dragons: Super Mario Bros. Edition, and Super Mario Maker and Super Mario Maker 2 in New Super Mario Bros. U-styled Underground levels. In New Super Mario Bros. 2, a woodblock is added if Mario/Luigi is in his Raccoon form, and in New Super Mario Bros. U and New Super Luigi U, the Baby Yoshis vocalize to the theme if players are carrying them.

An arrangement also plays in underground volcano levels in World 8. This rendition also returns in New Super Mario Bros. 2 in World 6-A, New Super Mario Bros. U and New Super Luigi U in Soda Jungle-5 and Peach's Castle-3, and in Puzzle & Dragons: Super Mario Bros. Edition.

It plays during the Clone Comet mission "The Shadow Lining" and the Double Time Comet mission "Turning Turning Double Time".
