Shifting to an examination of identity formation from below, Chapter 4 observes popular culture through music and opens a discussion on the nature of Iranian identity. Music is not only a cultural expression; in Iran it has also been used as a political tool and as part of resistance movements. Iranians voiced their allegiance with the revolution and their identity as Shiite Muslims through song-like protest chants and musical tracks. Protest chants and group singing heighten the meaning of words and help facilitate a sense of unity. These techniques were employed as an emotive force during the revolution and by later generations to proclaim their identity and as a form of resistance after the controversial election of 2009. The Green Movement is a pertinent example of how popular music is utilized by Iranians as a mode of expression. Consequently, popular music can be used as a tool for investigation in order to facilitate a better understanding of contemporary Iranian identity and society.
