The paper argues for the primacy of disciplinary knowledge in music education. We claim that the epistemic structure of this form of knowledge has two separate but ultimately interdependent functions. First, when used as the main principle in the design of the curriculum, such knowledge may be made accessible to students by being connected to procedural or practice knowledge. We introduce the term 'curriculum design coherence' to refer to the ways in which this connection is made. Second, the abstract nature of disciplinary knowledge contains two features, "generalizability" and "universalizability." These are pre-conditions for the creation of the collective representations that allow modern pluralist societies to cohere around the principles of democracy. In making the argument for a pedagogy in music education which combines "knowledge-in-the-mind" and "knowledge-from experience," we critique the current emphasis on experience to suggest that this approach does not provide the access to transformative knowledge despite claims for its democratic imperative.
