Musician-Teacher Collaborations: Altering the Chord explores the dynamics between musicians and teachers within educational settings, illustrating how new musical worlds are discovered and accessed through music-in-education initiatives. An international array of scholars from ten countries present leading debates and issues-both theoretical and empirical-in order to identify and expand upon key questions: How are visiting musicians perceived by various stakeholders? What opportunities and challenges do musicians bring to educational spaces? Why are such initiatives often seen as "e;saving"e; children, music, and education?The text is organized into three parts: Critical Insights presents new theoretical frameworks and concepts, providing alternative perspectives on musician-teacher collaboration. Crossing Boundaries addresses the challenges faced by visiting musicians and teaching artists in educational contexts while discussing the contributions of such music-in-education initiatives. Working Towards Partnership tackles some dominant narratives and perspectives in the field through a series of empirically-based chapters discussing musician-teacher collaboration as a field of tension. In twenty chapters, Musician-Teacher Collaborations offers critical insights into the pedagogical role music plays within educational frameworks. The geographical diversity of its contributors ensures varied and context-specific arguments while also speaking to the larger issues at play. When musicians and teachers collaborate, one is in the space of the other and vice versa. Musician-Teacher Collaborations analyzes the complex ways in which these spaces are inevitably altered.
