 A key difference in the soundtrack between the games is the inclusion of dynamic music for boss fights based on the progression in "Bayonetta 2".Ueda states that the music is broken up into phases and are set off by triggers based on animations and other cues in the scene which allow for swells in the music to match up the action onscreen.A similar approach was done for the stage tracks as well, with as many as 10 shorter loops mixed together that transition based on the player's progress through the stage.
