The document discusses different theories about how music videos relate to song lyrics. Andrew Goodwin's theory is that a music video is simply a visual interpretation of the lyrics. Carol Vernallis' theory is that a music video can be based on or tell a narrative inspired by the lyrics, and that repetition of ideas, themes and shots helps create meaning for viewers. The document also notes that editing in music videos allows jumping through time and space without seeming odd. Based on these theories, the evaluation concludes it is okay to be more creative than just matching the video exactly to lyrics, and that Carol Vernallis' theory allows for more flexibility.
