Elizabeth Lyon is a Ph.D. candidate in musicology and is currently completing a dissertation entitled, "Theorizing Music as Spiritual Practice: Perspectives from Augustine to Tinctoris." Her research centers on the history of musical thought, theory, and practice within medieval theological and philosophical contexts, particularly ways in which music theory intersects with medieval psychological frameworks for volition and affect. As a cellist and music director, she performs and teaches a wide range of Western art and sacred music, from new music to medieval office chants, in both university and community settings. She maintains an active career as both a baroque and modern cellist and has lectured and conducted workshops on eighteenth- and nineteenth-century performance practice. Her research has been published in Greek and Roman Musical Studies and the International Review of the Aesthetics and Sociology of Music, and her music criticism can be found in The Hudson Review.
