The Routledge Companion to the Study of Local Musicking, Routledge (2018). This chapter examines how marketplace factors affect programming decisions made within radio stations at the macro level, and illustrates their local impacts through a case study of the Chicago Independent Radio Project (or CHIRP). I argue that stations like CHIRP facilitate public intimacy and personal relationships in local spaces and places via imagined communities that are more social than they are imaginary. Through participatory musicking, their staff, volunteers, and listeners help construct musical locality together.
