This chapter considers the role of social media (broadly conceived) in the learning experiences of folk musicians in the Anglophone West. The chapter draws on the findings of the Digital Folk project, funded by the Arts and Humanities Research Council (UK), and begins by summarizing and problematizing the nature of learning as a concept in the folk music context. It briefly explicates the instructive, appropriative, and locative impacts of digital media for folk music learning before exploring in detail two case studies of folk-oriented social media: (1) the phenomenon of abc notation as a transmissive media and (2) the Mudcat Café website as an example of the folk-oriented discussion forum. These case studies are shown to exemplify and illuminate the constructs of traditional transmission and vernacularism as significant influences on the social shaping and deployment of folk-related media technologies. The chapter concludes by reflecting on the need to understand the musical learning process as a culturally performative act and to recognize online learning mechanisms as sites for the (re)negotiation of musical, cultural, local, and personal identities.
