Every form of dance from children 's jumping of joy , to ritual invocation of Gods of a tribe to theatrical performances, comes from the need of human beings to translate their feeling into motion. In every temples and in almost all the types of societies it is always demanded that the the dancers  before took over of traditional complex movements and so that they transform them into a dance exhibited with the looseness and spontaneity fixed in the sketch(1910)of Lev Bakst for the ballet Sherazade.   

In its most elemental forms , dance comes over from a natural instinct, from a sort of exigency to physically translate a whatever emotion: such exigency appears to be common to every population at every age: just to make an example, who from us does not have sooner or later 'danced of joy ' upon hearing a particularly joyful news?. But this spontaneous movements, although they mark the beginning of dance, are not yet 'dance'. Jumps standing on only 1 leg and the jumps on 2 comes closer to an artistic shape when the movements of the body obey to a definite rhythm. 

We can say that 'dance' effectively started beginning art when among the most ancient people , the spontaneous movements were gradually harnessed by rhythm, produced initially stomping your feet on the ground and later with the accompanying of musical instruments. 

Once set the steps in shapes and destined to express ideas and beliefs , some dancers started training in a way to render their body more agile and expressive .

We see dance to evolve itself in three distinctive  genres  : religious, social and theatrical : such genres by time have reached that grade of technical and artistic perfection proper of our days. 

Maybe it will be too big the distance that separates the primitive man that mimes the chasing of the prey from the splendour of an industry sacred dance or from the virtuosity and from the beauty of a ballet of Opera of Mosca. But everyone has something in common: the creation of a dramatic figuration through the expressive use of the body
