Find an music video as an example for each of Goodwin's point and explain just why it relates to the point.
For example
There is a relationship between the music and visuals.
In Chemical Brothers' Star Guitar the video is seemingly a view from the window of a speeding train. As video continues and the music becomes more layered it then becomes apparent that the scenery (pasting posts, buildings and trains) is a visual representation of the music - so posts become beats, colour tones change with volume and the pace of the train changes with the pace of the song.
The points you might have a problem with are:
3) Genres are complex and diverse in terms of music video style and iconography.
Choose a genre you like and are comfortable with and find a typical/conventional video for that genre. Explain why you believe it is a good example of the genre chosen in terms of performance type, iconography, narrative etc.
4) Record companies demand close-ups of performer and appropriate representation.
Choose a well known performer and find a video that which helps build their star persona (Marilyn Manson - weird, Olly Murs - cheeky chappy, One Direction - cheeky funsters etc) and explain why.
