This chapter examines the process of researching how to transmit musical heritage through the process of co-writing. The Transmitting Musical Heritage project team involved a number of different partners, all with particularly complex sets of skills. These interrelationships embedded between the academic institution and community partners had a strong impact on the project, its processes and its destinations. It involved varied approaches to practice and research, with the team and the co-producers, at times, occupying an amorphous zone where academics were academics, academics became musicians, musicians became academics, and musicians were also musicians. This community of practice was able to uncover tacit knowledge about playing and the process of making music together, as well as to unfold narratives about which heritage was valuable and why. This enabled a shared vocabulary of practice.
