This ethnographic study investigates creative dynamics in a musical creation laboratory at the University of Rio Grande, Brazil. Data collection was obtained through semi-structured interviews conducted after the accomplishment of free improvisation activities. The research focused on the testimonies of 10 volunteer musicians, emphasizing the expectations, transformations, and reflections present in their narratives. The findings highlight how emotional experiences shape musical expression, revealing the transformative role of creativity in both individual and collective artistic practices. The study revealed that the process of creative freedom was deeply influenced by the participants’ emotions. These emotions, when experienced and expressed, reflected meanings and reinterpretations in how they perceived and positioned themselves both artistically and socially.
