International School of Theatre Anthropology
From Wikipedia, the free encyclopedia
The International School of Theatre Anthropology (ISTA) is an international and multi-cultural network of performers, directors, scholars and academics of the theatre. Based in the Odin Teatret, Denmark, the organization has the nature of an itinerant university whose central field of study and research is theatre anthropology, the multi-cultural study of acting techniques.
Founded in 1979 by Eugenio Barba, the ISTA has functioned as a laboratory of theatre in the spirit of Grotowski theatre, though broader and more inclusive. ISTA researches the technical aspect of the performer's art by empirical methods to further the understanding of the fundamental principles which engender the performers' particular being and energy. This way of being, referred to as "presence" or "scenic life", is paradoxical. The 'daily' organic being is transmuted through often rigorous execution of techniques—which share a number of common features across a multitude of traditions—to come alive and new in the moment of performance once again, but at a higher level of energy.
The study of the common features of theatrical tradition in different cultures can facilitate the performance of the actor or actress.
Principles
Considering acting techniques around the world, Barba observed that the 'extra-daily' life of the performers is the result of alterations in the performers' balance, producing the appearance of a separate, unconscious autonomy.
