Andrew Goodwin developed a theory with 8 key parts for analyzing music videos: 1) Links between lyrics and visuals, 2) Links between music and visuals, 3) Genre characteristics, 4) Intertextual reference, 5) Notions of looking, 6) Voyeurism, 7) Demands of the record label, 8) Performance, narrative or concept-based styles. The theory states that lyrics should relate to visuals, visuals emphasize lyrics, and music links to visuals depending on genre. Genre also influences characteristics. Intertextual references draw from outside influences. Videos involve notions of looking into lives and voyeurism. Record labels demand artist appearances. Styles depend on genre and lyrics.
