The purpose of this instrumental case study was to examine preservice music educators' perceptions of teaching voice lessons to elementary and secondary students during an online synchronous fieldwork experience. I used Garrison et al.'s Community of Inquiry (CoI) framework to analyze the participants' perceptions of cognitive presence (i.e., triggering events, exploration, integration, and resolution), social presence (i.e., emotional expression, open communication, and group cohesion), and teaching presence (i.e., structure and design of the fieldwork experience). During initial lessons, participants cited mostly triggering events and exploration, which occurred alongside indicators of social presence. Participants cited technological challenges associated with online synchronous learning (i.e., teaching presence) may have hindered instances of integration and resolution. Music teacher educators may consider using the CoI framework to structure collaborative and supportive online synchronous fieldwork experiences.
