This study demonstrates how action research can provide a means for teachers to undertake research for themselves to inform and enhance their work. The focus of the research was the self-critique of pedagogical practice in one-to-one classical instrumental music teaching within the context of the author's private studio. A series of lessons were videotaped and analysed, and each week goals were set for the improvement of practice in relation to theoretical propositions derived from both one-to-one teaching and general pedagogical literature. The author is an experienced classroom teacher as well as a violin teacher so is well placed to explore potential links between these teaching contexts. The development of a model of teaching modes, greater awareness of feedback quality and type and the challenge of monitoring change in action emerged as the key themes. Student engagement increased and teaching was enriched by perspectives and practices from wider educational theory and practice. (Contains 1 table, 1 figure and 5 notes.)
