Jean-Georges Noverre is regarded as a great ballet-reformer in the 18. Century, although his way of thinking remains within the limit of the traditional, at most the typical philosophy of that time. His ‘Lettres sur la Dance et sur les Ballets’ are read not only as one of the important literature of the aesthetic of the enlightenment, but also as a book of instructions for the ballet-learning until today. However, some notions in his ‘Lettres’ have quite different meanings from these of today. Especialy the “passion”, the “nature”as well as the “imitation of the nature” are the most important notions in the Noverres aesthetic, Which were understood however in the middle seventeen hundreds differently from today and thus the stones of stumbling for us.
This research aims at clarifying the relation of Aikido, the Japanese martial art which has been pointed within many researchers as one of the roots of Contact Improvisation (CI), and the philosophy of Paxton, the founder of CI. With considering his dance works in 60's, the researcher examine how Paxton's work were different between before and after meeting with Aikido and how can we understand the nature of CI as a fruit from Aikido. Challenging to visual images in daily life or that the traditional dances had conveyed, Paxton had came to wonder the problems of dance, as performing art. Aikido caused significant answers to his questions about “exploration of senses” and “conveying information”. The answers that the researcher noticed are in the keywords of Paxton's writing about Aikido those are “information in deed”, “non polar ‘we’ ”and “those who have eyes to see”. By meeting with Aikido, Paxton found a form named CI that is not only accessible for various people but also has own technique and philosophy. With philosophical influence, based on “the principle of Centralization” of Aikido, people practice CI improvising freely “with an aim to working along the easiest pathways available to their mutually moving masses”. The concentration toward to this aim made it possible to train “fully consciousness” that would extend “the new ground for moving”.
