Music teachers seek imaginative openings to expand the reach and scope of the music curriculum, particularly by engaging more students in creative production and culturally relevant offerings. This article describes the work of a high school choral music educator who implemented new courses in Hip Hop Production by strategically navigating the policy process for course approval in his school district, informing the proposal with readily available data, consulting with colleagues, and aligning the purposes of the courses with district initiatives. As a case of music teachers' curricular agency, this story illustrates valuable orientations and principles of change that open up avenues for the expansion of music programs in the context of district-level policy environments.
