For several years, the practice of improvising clowning has been used as a support for a therapeutic-mediated workshop in an institution that takes in adult psychotic patients. The instructions given there insist on the here-and-now of the discovery of the object, through an enacted poly-sensoriality, as close as possible to the body. During the health crisis due to Covid 19, this workshop continued, with each participant at home, via a conference call, which necessitated the transition from a largely visual sensoriality to a predominantly aural sensoriality. The particularly constrained system, eliminating the visual dimension and linked only to the auditory canal, nevertheless allowed for a freedom of improvisation, the discovery of new possibilities, and increased reliance on the infra-verbal dimension, providing a support for figuration. The group envelope, reconstituted only by voices in telephone exchanges, was the second essential support for this unprecedented experience.
