Dance majors' dance emotional expressiveness is based on their body-emotion integration, which impacts their level of performance engagement. Through training to improve the expression of dance emotions, dance majors learn to identify and express their feelings. In this study, 507 Chinese majors in contemporary dance were asked to evaluate the relationship between dance emotional expressiveness and performance participation using emotional intelligence. The findings demonstrated a substantial relationship between dance emotional expressiveness and emotional intelligence, as well as a significant relationship between emotional intelligence and performance engagement. Furthermore, it was discovered that the relationship between dancers' emotional expressiveness and performance involvement was mediated by emotional intelligence. This study is important because it sheds light on the relationship between Chinese contemporary dance majors' performance engagement, emotional expressiveness, and emotional intelligence. This information will help develop better teaching strategies and curricula.
