Perception & interpretation is an modular sound workshop, open to everyone for one afternoon or more. I use games and simple pedagogic methods which stimulate the participants' cognitive functions on various levels. I have installed a set of situations & simple tools to observe and explore cognitive biases of the participants. These moments of participative sharing and exploration are marked by points of exchange, insight, and learning. I ask of the participants that they will have observed one of my performances the day of or days preceding the workshop, the performance being the first step on the road which, for a few hours, we will walk together.
