Student motivation is frequently an issue in general music classrooms, and many long-standing theories designed to increase motivation have the opposite effect. This article introduces Self-Determination Theory, first developed by Edward Deci and Richard Ryan, as a theory of human motivation. A key element of Self-Determination Theory is the concept of three basic human psychological needs: autonomy, competence, and relatedness. This article details each need and provides suggestions for direct applications to the general music classroom. Through the fulfillment of these needs, teachers can encourage and support a students' engagement in musical activities and personal growth.
