Music teachers should have opportunities to participate in professional development that focuses on their interests, learning style, and is relevant to classroom activities and goals. Online professional development allows teachers to participate in ways they see fit for their circumstances and can promote reflection and growth. Teacher-created online professional development is context-specific, inquiry-based, and includes components of choice and flexibility. Modern technologies, media, and web resources such as podcasts have provided new possibilities for teacher professional development. Podcasts offer multiple ways to support an individual's learning, and have potential to meet the characteristics of effective teacher-created professional development. The purpose of this intrinsic case study was to examine one novice music teacher's experiences using a self-created and produced podcast as a professional development tool. Research questions were: (1) How did the podcast contribute to this teacher's professional development?; and (2) How did producing the podcast influence his teaching practice? Three themes emerged: increased motivation and inspiration to improve, connecting with and learning from other music teachers, and Tenuto as a reflective resource. The podcast served as part of this teacher's Professional Learning Network (Bauer, 2010, 2014), providing individualized, sustained professional development experiences involving informal means of communication and collaboration.
