This chapter considers the development of systems to deliver multimedia content for new opera. After a short overview of the history of multimedia in opera, the specific requirements of opera are analysed, with emphasis of the fundamental musicality of operatic performance. Having considered the place of multimedia elements in the narrative and acting space, the relevance of previous practice in electroacoustic music and Vjing is considered as a model for a working approach. Several software and hardware configurations explored, including the use of gestural control by the actors themselves. The creation of a keyboard based “video instrument” with a dedicated performer, capable of integration into the pre- existing musical ensemble, is recommended as the most effective and practical solution.
