A collaborative piece of theatrical music with
Paulo Maria Rodrigues and Luís Girão, Portugal
It is a structured improvisation that develops from a personal journey of discovery on the potential of the interaction between a performer and a computer. At the root of the performance lies the traditional “classical” singer’s clothing, the tails, which has been transformed to host a set of electronic controllers that communicate with a computer. CyberSong explores the challenges of meeting “classical’ music (the sound utterance, the theatrical context) with new technologies (which causes the redefinition of the role of the performer/interpreter/composer). CyberSong involves a singer/actor that processes his own musical discourse in real time. There is a set of “sound objects” and “theatrical actions’ (including the musical/theatrical treatment of scientific/artistic relevant texts) that serve as departing points for a dialogue between the performer with his memories (instant or long-term) and the gesture that results from the electronic manipulation of the sounds.
