Although "entrepreneurship" has become a movement in arts career preparation programs, its application for school-based music educators remains unclear. This article suggests that "intrapreneuring"--entrepreneurial practice within large organizations--better encapsulates the balance of innovation and affiliation that teachers often pursue to enhance their motivation at work. Results from a survey of K-12 music educators suggest that intrapreneurial mindsets and behaviors predict higher fulfillment of teachers' needs for autonomy, competence, and relatedness--all elements crucial to healthy motivation. For many music educators, intrapreneuring may serve as an ideal pathway to increased motivation, career longevity, and a broader teacher-driven approach to education reform.
