This study analyzes the dance work “Concept” and how its creative process -- how it was planned, choreographed, and performed by the researcher. It examines how the core theme ”Concept” was expressed throughout the stages of composing, choreographing, and performing, and how the ‘dépaysement’ technique was utilized. “Concept” is both the subject and title of the work, while dépaysement is used to choreograph movements. The study investigates how surrealist expressive characteristics, thought processes, work intentions, and the dépaysement technique were reflected in each creation stage, using a practice-based research method. Results showed that in section 1, ‘The Layers of Memory,’ ‘isolation,’ ‘paradox,’ and ‘image as a visual form’ were used to create an optical illusion of dancer's movements. Section 2, ‘the Texture of Mind’, used ‘polarity of concept,’ ‘transformation,’ and ‘synthesis’ to show transformation according to changes in the movements. Section 3, ‘The Distance of the Street’, used ‘change in size’ and ‘a chance of an accidental meeting’ to achieve a harmonious combination of the object and the dancer. It is hoped that this article will inspire choreographers seeking new methods to develop their dances.
