The document analyzes the soundtrack of the game Call of Duty: Ghosts. It describes how the music establishes a sense of accomplishment after completing a beach mission, but then takes a sinister turn when the main character is dragged away by the antagonist. It states that different sounds were likely merged to create the calm initial music, which then gets louder and lower in pitch as the mood shifts. The changing pitch and removal of calm sounds creates a darker atmosphere to match the narrative as it transitions from a happier ending to a more sinister development.
