Synchronization between rhythm and motion is indispensable for both communication in man-machine interface and the efficiency of joint working. In this study, as a fundamental study of the rhythm-motion synchronization, beating a drum in synchronization with an electronic sound or a music is selected. The object of this study is to develop a quantitative method for analyzing the rhythm-motion synchronization, and to demonstrate its effectiveness in terms of sensory evaluations. In the case of the synchronization of motions with a constant rhythm, it is found that motions lead the rhythm, independently of the kind of music and the beating of the rhythm. It is proposed that variability in cardiac cycles of subjects is effective as one of the indices to the working control. In order to grasp the internal state of subjects, electro-cardiogram is measured. It is found that the closer the period of the rhythm is to the characteristic rhythm of the subject, the easier the rhythm-motion synchronization becomes, that is, the less the workload becomes.
