Through a duoethnographic study (Norris, 2008), Caitlyn, a newly graduated music educator and now masters student, and I, a seasoned music educator and new music teacher educator at Caitlyn's alma mater, collaboratively explored the experience of preservice teaching from our divergent roles and generational perspectives. Seeking to understand development of "music teacher agency," we entered into a process of duoethnographic dialogue journaling as a primary data source. Ascribing to the tenets of this innovative qualitative methodology, we created and interrogated interwoven dialogic narratives as we mutually investigated curricular approaches to and practices of the last year of preservice music education. The co-constructed process of duoethnography (a) enabled us to synthesize theory and research method with practice; (b) fostered development of professional identities through reflection within equitable and collegial relationships; (c) and potentially mitigated fears as each participant experienced emancipatory dialogue toward positive change, heightening music teacher agency.
