This conference will draw together scholars, practitioners, and scholar-practitioners across music theory, musicology, ethnomusicology, performance studies, music cognition, public music theory and related fields, who use interviews, (auto)ethnography, and other quantitative and qualitative methods to understand how musicians across a range of practices conceptualize what they do, in dialogue with or distinct from institutionalized music theories. Featured speakers include Jonathan de Souza, Jason Rawls, and Leslie Tilley.
