Contact improvisation (CI) is a form of improvised partner dancing
that has been developing internationally since 1972 by American choreographer Steve Paxton.
He was a dancer with a background in tumbling and martial arts, and was a member of several modern dance companies in New York in the 1960s.
CI involves the exploration of one's body in relationship to others by using the fundamentals of sharing weight, touch, and movement awareness.
CI practice includes rolling, falling, being upside down, following a physical point of contact.
It has evolved into a global community of social dancing around "jams" and is often found overlapping with ecstatic dance communities.
