Abstract

The purpose of this research was to explore how post-ableist music therapy can be used to support non-speaking individuals in asserting their right to agency. A philosophical inquiry methodology was chosen to examine the experiences of non-speaking individuals and to challenge assumptions and unquestioned beliefs within systems that often contribute to the oppression of those they are intended to support. To do this, a review of existing scholarly, grey literature, and activist sources was conducted to critically analyze the assumptions surrounding the capacity for agency, the agency needs of non-speaking individuals, and post-ableist music therapy, examining how its core principles position it as an ideal approach for supporting non-speaking individuals in asserting their right to agency. The literature was organized into a synthesis matrix, coded for common themes, and analyzed in detail within the thesis. Findings suggest that a post-ableist, PAMT-informed music therapy approach can support the agency of non-speaking disabled individuals by reframing agency as relational and collaborative while challenging ableist norms. The discussion highlights findings on communication, lived experiences, and representation, as well as implications for practice, education, research, and social justice.
