In “The Alibi,” Serial utilizes music to heighten mood in different parts of the narrative. They open with a sharp, high-pitched piano tune that keeps you on your toes, which goes along with the narrative of a somewhat unsolved murder case. The combination of dialogue and exposition gives the essence of a clearer narrative where listeners can visualize the setting, in a way that is different from print or video. This makes the podcast more engaging. Hearing only the participants’ voices, listeners can hear their emotions rather than see them, which heightens these emotions in a different way. As a medium, sound has its own unique way of affecting our emotions, and this is made clear by how podcasts work.
