In this article, the theoretical framework of developmental pedagogy is presented as a tool in studying and developing children's knowing within the arts. The domains of art focused on are music, poetry and dance/aesthetic movement. Through empirical examples from a large-scale research project, we illustrate the tools of developmental pedagogy and show how this perspective contributes to our understanding of children's learning of music, dance and poetry. More specifically, we will analyse: (a) the important role of the teacher in children's learning within the arts; (b) the importance of conversing when learning the arts; (c) what constitutes the knowledge, what we refer to as "learning objects", to be appropriated within the three domains of art focused on; and (d) how to conceive of progression in children's knowing within the arts.
