A summary of the main points of Andrew Goodwin's theory

In Goodwin's theory, he identified a number of key features which distinguish the music video as a form. They are:

• A relationship between the lyrics and the visuals, with the visuals illustrating, amplifying or contradicting the lyrics.
• A relationship between the music and the visuals, with the visuals illustrating, amplifying or contradicting the music.
• All genres are complex and diverse in terms of music video style.
• Record companies will demand a lot of close-ups of the main artist or vocalist. This helps the audience see and identify who the main artist is (and most probably what they are about)
• Voyeurism isa factor present in music videos. For example:The  treatment of females, and also in terms of systems of looking. Some examples are screens within screens, cameras, mirrors and etc.
• It is likely to include intertextual references, either to other music videos or to films and TV texts, these provide further gratification and pleasure for the viewers/fans.

So an example of illustration in a music video could be ''Papa dont preach'' by Madonna. Just like other forms of illustraion within music video, papa dont preach has a narrative within the video that relates to the lyrics in the song and tells a story.
