This introductory course on the art of acting is practice-based. It aims to familiarise students with the main issues of stage expression, a field that is constantly being renewed by the emergence of new ideas or aesthetic and ideological trends. However, from the traditional actor of dramatic theatre to the contemporary performer, across the different traditions and forms of acting, certain principles remain common: presence, address, inventiveness, form, gesture, voice, physicality, event, space are some of the principles of stage performance that we will attempt to explore with the students in an practice-based way.
