This study is concerned with a correlation between the image of shop made by the collaboration of shop space and BGM, and a customer"s relaxation. The environment which a customer can relax is demanded in a shop like a beauty parlor. Song selection of BGM and a space design are important for it. Then, in order to measure correlation between the image of a shop and a customer"s relaxation in an experiment, the set which imitated the beauty parlor was considered. It projects the image of a beauty parlor on the screen of three directions, and also sounds music from the speaker installed in the ceiling. In the experiment, five genres of music (Classic, Jazz, Bossa Nova, Hip Hop and Rock) and four kinds of space (Fresh image, Warm image, Noisy image and Simple image) were prepared. The subjects experienced five genres of music, four kinds of space, and 20 kinds of combination at random, and the subject"s impression was written down in the evaluation paper. As a result, music had influenced the customer"s relaxation. At the shop which offers a relaxation to customers, music of Jazz or Bossa Nova and a warm space are effective. Simultaneously, music of a Rock and a noisy space checked that it was not effective, either. Furthermore, when making the space design of the shop the simple space, it has checked that an impression and a customer"s relaxation was also changeable only by song selection of music. Finally, when designing the shop which provides a relaxation to customers, comfortable, become composed, and peace of mind are important elements.
