The music was composed by Grant Kirkhope, who previously worked as the main composer for "Perfect Dark", "Donkey Kong 64", and "Banjo-Kazooie". As "Banjo-Tooie" was a larger game than its predecessor, Kirkhope had twice the memory space in the game's cartridge for sound effects and music. Kirkhope initially had to pause his work on "Banjo-Tooie" to work on other projects first, but ultimately the music score for the game was completed on time. Like the game's predecessor, the themes heard in the game were designed to be interactive, which dynamically change to reflect the player's location. Due to the game having larger memory space, Kirkhope was able to combine two MIDI files to channel different fades of music when the player moves to different locations. The developers initially aimed for a fourth quarter 1999 release, but the game was ultimately delayed. "Banjo-Tooie" was presented at the 2000 Electronic Entertainment Expo and first released on 20 November 2000 in North America. Japanese and European releases followed on 27 November 2000 and 12 April 2001, respectively. The game supports the Nintendo 64 Rumble Pak.
