A study was conducted to investigate the characteristics of dance pieces from the viewpoint of the imagery communicated through two pieces of modern dance, "Requiem" and "Nocturne", which were choreographed by the author and won a prize in a national dance contest. In order to determine the imagery characteristics, the 46 semantic differential scales used in the study by Zukawa et al. (1980) were used. The dance imagery was investigated through factor analysis applied to a 46 × 46 correlation matrix obtained from an experiment in which 49 female subjects (36 high school students, 10 college students, and 3 experts) were asked to respond to two dance pieces with 46 semantic scales. The following results were obtained. 1. In "Requiem", the following 14 factors were extracted: aesthetics, vividness, dynamics, harmony, tensity, emotional distance, difficulty, attitude,delicacy, regularity, originality, liveliness, spatial distance, sensation. 2. In "Noeturne", the following 13 factors were extracted: dynamics, emotion, aesthetics, vividness, harmony, tensity, rhythmicity, spatial distance, originality, distance, acuteness, attitude, delicacy. 3. These extracted factors were classified into three image domains-sense domain, sensibility domain, and feeling domain-which were assumed to be constructs of the imagery. These three domains were independent of each other in each of the pieces, and similarity in the three domains between the two pieces was investigated using canonical correlation coefficients. High similarity was found in the sense domain between the two pieces, and low similarity in the sensibility domain; there was no degree of similarity in the feeling domain. It was concluded that the uniqueness of "Requiem", which is a direct expression of sadness, was realized by movements suggesting regularity, liveliness, and difficulty. The uniqueness of "Nocturne", which expresses a mind journey in the darkness of night, was realized by movements suggesting emotion, acuteness and rhythmicity.
