Conventional studies indicate that the strength of crossmodal correspondence, which represents the connection between multiple senses and actual human perception, may influence pleasant or unpleasant emotions in some combinations of sensory modality and stimulus type. In this study, sensory evaluation experiments were conducted to evaluate the crossmodal correspondence between visual and auditory sense mediated by 'complexity' using closed curve shapes and tone sequences generated based on curvature entropy and tone entropy. The relationship between the sensory evaluation values of the 'aesthetic preferences' of the shape/tone sequence combinations and the weakness of crossmodal correspondence, that is, the difference of curvature and tone entropy, was fitted to the Wundt curve, one of the models of pleasant emotion. As a result, a strong correlation (0.64) was confirmed between the two. Bias due to the musician's experience was confirmed in the sensory evaluation values of some tone sequences.
