Western Dance – Hip Hop & Freestyle
is a way of dancing in which the dancer improvises his moves on the spot, as he dances, instead of having them planned beforehand (ie choreography).
In its most extreme form it is the very opposite of choreography, however it can be argued that such an extreme level can never be reached, as we all to some degree plan our moves beforehand. To give an example, one might put on a piece of music and start freestyle dancing to it, but having heard the piece before, and having practiced different moves earlier, one can never 100% freestyle to it.
Having heard the music before, one is bound to unconsciously plan for different parts of it, and the moves that have been choreographed beforehand will inevitable be a part of the dance.
