Although dialogue is a great way to tell a story, it will only entertain for so long before visual and audio aides are needed to keep the story interesting. The elements in the video speak louder than words. Both visual aides, and audio can tell a story without the need for words to ever be spoken. Visual elements are especially important. What is seen by the actions of the characters and the background elements can tell a story by keeping everything in a relatable context.

Music has a history of evoking emotion. There are certain sounds that key us into the context of a scene such as Richard Wagner – Ride of The Valkyries which clues us into an impending battle, or on a darker side the Sequential: Dies Irae tells of death and despair, and on a brighter note Beethoven – Symphony No. 9 in D minor: Ode to Joy tells of happiness. These are just a few of the songs that have been used for many years to sway emotion in storytelling
