This study focused on time, space, and weight from the perspective of good movement in rhythmic dance. The effect of guidance was verified. Specifically, the following two research subjects are presented: i.e., (1) we examine the change in rhythmic dance skills after an explanation about the three perspectives of good movement; (2) we examine the change in rhythmic dance skills using the breath (e.g., onomatopoeia). As a result, the following three points were clarified: (1) dance skills were improved by explaining good movement from the perspectives of time, space, and weight; (2) in being conscious of breathing (onomatopoeia) during rhythmic dance, it is easy to express rhythm with the body and it is effective in improving timing skills; and (3) dancing while sounding onomatopoeia has the potential of improving emotional aspects, predictive/judgmental abilities, and memory.
