Archer argues that every music video will switch between performance and narrative.
He says that the video will contain a dance sequence or element of repeatability in it. Such as in the case of Soulja Boy's 'crank Dat' (www.youtube.com/watch?v=8UFIYGkROII )
He states that it is normal for the artist to be a part of the narrative as well as the performance, however extra emphasis will always be given on the artist carrying out his craft of music making to reinforce the idea that these guys or girls have a really close relation to their music. This kind of theory is mostly found in country and indie songs, as there is a strong emphasis on the lyrics and their meanings. For instance Taylor swift in this picture you can see has a real attachment to her instrument.
