Contemporary dance and plastic practices, which belong to an aesthetic of presentation, invite us not to add, to inflate the flow of life and thus not to slow down or to double the reality of another real fact of consciousness and representations necessarily different. In these practices of intensity, the notion of experimentation is important and gives full meaning to practices that do not favor results, the formal resolution of the work, but rather the dynamics of a proposition in action. Experimenting does not consist in composing dead objects but in implementing, in the immediacy of the moment, the sobriety of a direct contact with the raw reality. Duplication, which is a factual reality, tends to constitute itself as a rejection of the singularity of reality.
