Larkin chose the instrumentation for each track based on the various digital environments in the game. When the player is in the game's representation of New Mexico, for example, Larkin used a resonator guitar and flutes, creating what he called something "indigenous to a southwest type of feel that's very contemporary". In other areas Larkin described the game's music as being "less typical than you would find in most games" because of the exotic landscape the developers had created. To create contemporary and exotic types of music in the game, Larkin employed a combination of real and synthesized instruments. Sometimes Larkin replaced synthesized performances with those of real musicians, as in the track "Gallery Theme", where a synthesized vocal part was eventually discarded in favor of soprano Tasha Koontz. To create an exotic feel, Larkin used a group of Maasai tribesmen's chanting, who were recorded during their visit to Spokane, Washington, where Cyan Worlds was located.
