The region themes consist of six Music Playlist Containers, each with 3 to 10 Music Segments, plus a seventh Music Playlist Container reserved for silence. The region music is designed to switch the entire music composition based on a state. This means that when entering a different music region, the Music Switch Container will change from one Music Playlist Container to another. As the Music Switch Container is linked to a State, only one of the region themes will be active at once.
Whenever the player is outside of a Music Trigger, a more melodically passive theme, 'Ambient', is used while the player makes their way to the next area.
