Although much has been written about professional development in general education and music education literature, little has addressed the benefits of music-making as meaningful professional development for music teachers. For music teachers, music-making and meanings of music-making have been connected with teachers' identity, well-being, beliefs, and effectiveness, as well as being a powerful pedagogical tool and a way to develop presence in teaching. Presence in teaching is linked with self-awareness, attentiveness, and pedagogical knowledge. The purpose of this article is to explore the benefits of music-making for music teachers in order to convince policymakers of the value of music-making as a professional development activity for music teachers. This article explores theories from psychology and education that link engagement, well-being, and identity to lay the foundation for a justification of broadening professional development policies. Then, literature is presented that connects teachers' art-making experiences (past and present), identity, teaching, and student learning. The third section draws on my previous work to illustrate the intersections between teachers' music-making and teaching. Then, suggestions for implementing professional development programs with music-making components are made. Although there are many ways music-making could be included as professional development, I offer four suggestions: including music-making in departmental or district-wide meetings, granting professional development credit to music teachers who make music outside of the classroom, setting up in-classroom reflection opportunities/action research based on integrating music-making and music teaching, and initiating a collaborative teacher study group that includes chamber music collaboration.
