The purpose of this study is to propose a new method for identifying the relationship between physical information (cognitive elements) about body parts that constitute classical ballet movements, and viewer impression. In order to uncover the quantitative relationship between the cognitive elements of ballet poses and impressions, the Affective engineering method (rough sets) was used to explore the human cognitive evaluation structure.
Among impression words, we focused on three antonyms (A. “dynamic ↔ static,” B. “linear ↔ curved,” and C. “well-intentioned ↔ ill-intentioned”), which were expected to be deeply related to the choreography of “Swan Lake.” According to the examination results of the impression words, the three antonyms A., B., and C. were classified based on the decision rules and each of the 19 silhouettes was classified into two different fields. The characteristics of A. “dynamic” was “stretching up high,” “balancing on one leg,” and “lifting the lower limb up high.” It represents ballet movement forms such as “arabesque” and “attitude” (movement lifting the leg up high behind the dancer). The characteristics of B. “linear” was “symmetric cross.” In other words, a strong “linear” image was drawn in the form of a cross. The characteristics of C. “well-intentioned” was “a vertically long shape, with hands rather closed.” This is similar to the everyday movement of straightening oneʼs back and positioning one hand on top of the other around oneʼs lower abdomen in a formal setting. These observation results helped verify through cases the effectiveness of the proposed analysis.
