This chapter situates the study of music teacher education within the larger body of music education and teacher education research. It problematizes the terms teacher training, teacher education, and best practice and introduces the concept of teaching as an “impossible profession.” Goals of teacher education, including reflective practice and adaptive expertise, are discussed. The chapter outlines the challenges that music teacher educators face as they try to prepare preservice teachers for the realities of P-12 school-based music education while instilling in these new colleagues a disposition toward change. It concludes with narratives that examine teachers’ descriptions of classroom relationships throughout the lens of presence in teaching as a way to remind teacher educators of the importance of their work to push the boundaries of music teacher education in order to serve the profession at large.
