概要	The purpose of this research is to show movement characteristics of bodies during dance performance. We examined bodily characteristics of dancers when moving and conforming to other dancers. Specifically, we analyzed paired dancer movements through motion capture and compared all body-part characteristics based on data derived from cross-correlation analysis and variance-covariance matrix using an exponential map. We found that the correlation coefficients of speed between the head, shoulders, and knees of dancers were significantly high. The values of variance-covariance through the exponential map based on velocity were positively high between the shoulders vertically, and the hips and knees in a front-back direction. The results indicated that not only the legs but also the shoulders of both dancers move at a similarly fast rate when they coordinate and synchronize with one another.
