Dance improvisation as a choreographic tool: Improvisation is used as a choreographic tool in dance composition. Experimenting with the concepts of shape, space, time, and energy while moving without inhibition or cognitive thinking can create unique and innovative movement designs, spatial configuration, dynamics, and unpredictable rhythms. Improvisation without inhibition allows the choreographer to connect to their deepest creative self, which in turn clears the way for pure invention. This cognitive inhibition is similar to the inhibition described by Limb for musical improvisation, which can be found in the music section above. Contact improvisation: a form developed in 1973, that is now practiced around the world. Contact improvisation originated from the movement studies of Steve Paxton in the 1970s and developed through the continued exploration of the Judson Dance Theater. It is a dance form based on weight sharing, partnering, playing with weight, exploring negative space and unpredictable outcomes. The skills of improvisation can apply to many different abilities or forms of communication and expression across all artistic, scientific, physical, cognitive, academic, and non-academic disciplines. For example, improvisation can make a significant contribution in music, dance, cooking, presenting a speech, sales, personal or romantic relationships, sports, flower arranging, martial arts, psychotherapy, and much more. Techniques of improvisation are widely used in training for performing arts or entertainment; for example, music, theatre and dance. To ""extemporize"" or "ad lib" is basically the same as improvising. Colloquial terms such as "let's play it by the ear", "take it as it comes", and "make it up as we go along" are all used to describe "improvisation". The simple act of speaking requires a good deal of improvisation because the mind is addressing its own thought and creating its unrehearsed delivery in words, sounds and gestures, forming unpredictable statements that feed back into the thought process (the performer as listener), creating an enriched process that is not unlike instantaneous composition [with a given set or repertoire of elements]. Where the improvisation is intended to solve a problem on a temporary basis, the "proper" solution being unavailable at the time, it may be known as a "stop-gap". This applies to the field of engineering. Another improvisational, group problem-solving technique being used in organizations of all kinds is "brainstorming", in which any and all ideas that a group member may have are permitted and encouraged to be expressed, regardless of actual practicality.
