This volume brings together contributions from musicology, philosophy, cognitive science, and performance studies to explore how emotional content in Early Music can be understood and interpreted. Topics include philosophical and aesthetic theories of the passions, reflections on the Affektenlehre and its historiography, vocabularies of emotion in musical and non-musical sources, approaches from the history of emotions, and performative perspectives on historically informed interpretation. The essays reflect the diversity of ways in which emotional content in Early Music can be studied today, offering performers and scholars fresh perspectives on the ways Early Music\'s expressive dimension can be approached and interpreted.
