For the past ten years, through residencies and artistic creations, the Synekine Project has invited performers to question the intimate relationship between vocal gestures and manual gestures through the manipulation of scenic devices based on new technologies. Metaphorically, the pre-eminent neuromotor link between voice and gesture is closed by “creative prostheses” joining the capture of movement to the transformation of the voice by artificial intelligence. Linking space and time through movement then transforms the search for sound into a scenic exploration. This unit provides a retrospective panorama of this experimental research in a narrative oscillating between theoretical questions, technological innovations and artistic productions.
