In this article, we report an instrumental case study of extracurricular music education as an arena and means for securing the capability for selfdetermination among Finland's Indigenous Sámi population. Finland's egalitarian approach to education is rooted in complex, and at times contradictory, colonial legacies, raising questions as to whether or not mainstream education systems afford the Sámi the capability to enact their human and constitutional rights to sustain and develop their own languages, cultures, and worldviews. Through a critical analysis of international and national policy documents, and interview data from four Sámi music educators in Finland, we consider the capability for Indigenous self-determination as essential criteria for enacting social justice in, and through, music education.
