The document discusses three main forms of music videos: 1. Amplification videos use surrealism and interpretation to add hidden meaning and symbolism to the lyrics in a connotative way. 2. Illustrative videos contain narratives and/or performances that clearly visualize and denote the meaning of the lyrics. 3. Disjunctive videos take a completely abstract approach, with no direct link to the song or its lyrics, using repetition of dances or movements.
