The contributions in this volume reflect the efforts of musicology to understand a hybrid area with a fascinating evolution. They aim to address the relationship between opera and audiovisual technology from its origins to today by offering the results of a balanced critical and innovative approach. The reader interested in opera, aesthetics, narrative or transmediality will find concrete approaches devoted to an unexplored diversity of aspects with an impact on the narrative conditions in which we watch opera on screen. The variety of perspectives shows how original methodological approaches are able to design a new map of the main transmedial problems of opera in TV, DVD and even in phonography. The book offers not only isolated theoretical contributions but seeks a connection of them with significant practice oriented approaches coming from the fields of video direction and composition.
