The first section of the handbook conceptualizes social justice while framing its pursuit within broader contexts and concerns. Authors in the succeeding sections of the handbook fill out what social justice entails for music teaching and learning in the home, school, university, and wider community as they grapple with cycles of injustice that might be perpetuated by music pedagogy. The concluding section of the handbook offers specific practical examples of social justice in action through a variety of educational and social projects and pedagogical practices that will inspire and guide those wishing to confront and attempt to ameliorate musical or other inequity and injustice. Consisting of 42 chapters by authors from across the globe, the handbook will be of interest to anyone who wishes to better understand what social justice is and why its pursuit in and through music education matters.
