In addressing emotional states, this paper advances the notion of structural analysis of university level modern dancers’ emotion as a key factor in moving up the educational values of dance and developing effective dance performances. Phenomenological methods which can represent and interpret the emotional states of dancers have been used for the analysis method of this research. The participants in the study were five university students with at least five years of career as modern dancers. The data was collected through in-depth interviews and observation of participants. The empirical results suggested that the two main category of emotion are physical conditions and psychological conditions. For the physical conditions, two subcomponents were emotions caused by a physical phenomenon and by physiological phenomenon; for the psychological conditions, two subcomponents were emotions caused by external events and internal events. Through the results of analyses, it was evident that the control of lesson contents was necessary according to dancers’ physical conditions. The increase of curriculums for individuals to have more interest was also needed in order to enhance efficiency of dancing activities. Furthermore, university level modern dancers need to seek ways to control their conditions and understand, moreover, analyze motions, instead of burdening themselves from contests or performances.
