Improvisational structures permit the dancer elements of freedom and creativity in making movement and dances. The dancer can employ any number of  strategies and creative responses to pursue an outcome where the result is not fully known, for example

• a floor plan which is ‘scored’ but in which the movement is unknown; or
• where the movement is designed but the floor plan is open and the dancer is given the freedom to make the spatial decisions.

Other decisions might affect the timing, the choice of music and any elements of BEST.
