The chapter describes how mobile technology is firmly planted in young children’s everyday lives as they watch YouTube videos and play with apps that entertain and educate. Yet the question remains, What is the role of mobile technology in early childhood music education? There is concern that technology will compromise the active, playful musicking of young children. Mobile devices, however, can be used to support music development, with digital music play working in tandem with traditional music play in the form of converged music play. This chapter describes the ways in which early childhood teachers can incorporate mobile technology into their practice, extending its use to young children’s musicking in early childhood music settings, at home and in play spaces.
