Why are we learning both techniques?

I think that we are learning both techniques for a few different reasons. One reason i think we are learning both techniques is to give us an understanding of how people use to dance a while back to now and to show how insiprational both people are to these styles of dance. Also i think we are learning them not only to see how insiprational they are but to teach us new skills that we haven't learnt before. Another reason i think we are learning these technques is to shows how completly different they are; Martha Graham uses her dance techniques to show alot of emotion in the body, i think her moves are every flowy for example if she wanted to show pain from standing to low she would make sure that the body would flow from head to toe. This emotion could be dissapointment, upset, lonely or show no confidence but this emotion would all flow and set an atmoshpere according to the emotion. Whereas Cunningham is a every force movement person and he restricts parts of the body from moving. He took all of Martha's flow and made it masulin, tense, strong. For example the twist's and spins in his techniques all have to be every strong and forceful, no flow. both techniques are every different and i believe we are learning them to see the difference, to understand how different the two people are, even though Cunningham got taught by Martha! It just goes to show that Cunningham wanted to make it his own and make it unique to anyone elses.
