Which composer created the music for Super Mario Bros.?

Koji Kondo created the music for Super Mario Bros. and also produced the game's sound effects.

Released in 1985, Super Mario Bros. was one of Kondo's first major Nintendo scores. He designed its music to match Mario's movement, jumps, enemies, and changing gameplay conditions rather than treating the soundtrack as background decoration. The famous overworld theme uses a lively Latin-influenced rhythm, while the tempo accelerates when the timer runs low.

Kondo composed the six-track score during development, working closely with director Shigeru Miyamoto. The music was written for the limited sound hardware of the Famicom and NES, yet its melodies became among the most recognizable in video-game history.

A common mix-up is confusing Kondo with Hirokazu Tanaka, another important Nintendo composer and sound designer. Yoko Shimomura and Nobuo Uematsu are also celebrated Japanese game composers, but they were not the composer credited with Super Mario Bros.' original score.
