Music-based group interaction (MGI) is a complex social phenomenon that is important for individuals' emotional experiences. However, research on emotion in tourism lacks a focus on group interaction integrating the mind and body. Guided by Damasio's neurocognitive-evolutionary theory, this study used an adapted go-along method at Midi Festivals to analyze festivalgoers' emotional experiences during MGI. Meanings of the body and its agency-related roles were captured between emotions, music, and group interaction. Results revealed three patterns of MGI—dissociative, reflective, and immersive—based on the extent of congruence between social and bodily rhythms. MGI allows participants to achieve a clear sense of self and shared belonging thanks to the unity between body and mind. The findings provide insights into contemplating emotions, the body, and group interaction within a musical context. Results suggest that music tourism holds value for enhancing individuals' emotion regulation and well-being, offering implications for practitioners in event management.
