This study considers audiences contextually and historically, through both qualitative and quantitative empirical research, and places them within appropriate philosophical and socio-cultural discourses. Ultimately, the collection marks the point where audiences have become central and essential not just to the act of performance itself but also to theatre, dance, opera, music and performance studies as academic disciplines. This Companion will be of great interest to academics, researchers and postgraduates, as well as to theatre, dance, opera and music practitioners and performing arts organisations and stakeholders involved in educational activities.
