Goodwin's 3 types

There are 3 key forms to a music video and they usually overlap within one.

1. Performance
2. Narrative
3. Concept

Performance is the artist performing in the actual video, this can be from singing to playing instruments. This is a key factor in a music video as it allows the audience to see the artist performing whilst creating a sense of live performance.
Narrative is whether or not the events within the music video have a meaning, is there a fundamental story to follow? A key convention of this is by one character being tracked.
Finally Concept, this is when their is an overall idea within the video, despite the fact that it may not have a storyline or fit in with the lyrics.
