This creation process is added to the research developed within the framework of the CIRCULAR SABERES Y PRÁCTICAS DANZARÍAS (CIRCULAR KNOWLEDGE AND DANCE PRACTICES) seedbed, which was under the direction of Carlos Martínez, and where an exploration was carried out from the perspective of the body as a creative composition. In the seedbed we were playing different roles throughout the construction of the work, "La Ética de Creer" (The Ethics of Believing). From this, our particular interest in investigating the impact and role that affects have in the creative process, focusing on the conception of the body as a means to compose dance works. From the role of interpretation arises a constant conversation with our body, which leads us to examine in depth how emotions, feelings and affective states influence the gestation, composition and evolution of a choreographic piece. Our degree work is based on a qualitative approach that combines theoretical analysis with the practical experience of the dancer-performer as creator-choreographer in the staging of this specific work. Various theories on the relationship between affect and artistic creation are examined, as well as key concepts around the body as a site of expression and communication. This work offers an enriching perspective on the role of affect in the construction of the dancer's interpretation in the work "The Ethics of Believing", emphasizing the importance of the body as a channel for artistic expression and composition.
