ボールルームダンスにおけるヴィエニーズワルツの基礎解析

抄録

Viennese Waltz Dance in international style is analysed in the mechanical point of view. The movement of dancers is compared with that of English Waltz. Difference between Natural Turn and Reverse Turn is cleared. The exchange in the kinetic energy between translational movement and the rotational movement is dominant in the Viennese Waltz whereas the exchange between the potential energy and the kinetic energy is more essential in the English Waltz. Rise and Fall and the sway are analysed. Natural Turn, Reverse Turn and Change Steps are studied showing the trajectories of each dancer together with kinetic energies and mutual force between partners to match mechanically smooth movement.
