Hi Sekar!

Thanks for your question! I would put it into these words what is the creation theory of dance choreography?

This is a broad question since the art of dance has many époques. But if look at from general view a dance composition includes movement, pause, silence, space, stage, light, person (people), body, costume, face, gesture, voices of body movements, music (if there is).

And most importantly "your message" that you want to express which all starts from there. Then you can research data of choreographies that executed about this theme. You can imagine/draw/write/ your taste, then starting from the duration to space to quantity of person etc. you compose your work.

I hope this answer gives a bit help.

Have a good day!
