This paper attempts to analyze Visual Music-type works, which is the area of ​​my creation, from the perspective of cognitive science. After that, we tried to apply the derived analysis results to all Visual Music type works that span audiovisual sensation. First, he mentioned the series of processes leading to the overall institutionalization of the various elements created by human cognitive function, that is, the formation of gestalt, which is created by recombining them. Next, I tried to explain the work from the viewpoint of cognitive science, taking as an example a work that is characterized by this change in Gestalt. Then, it was possible to clarify that these works effectively promote the intention of the work by skillfully utilizing the erroneous function in brain processing. Based on these verifications, he described his completed work "unseeable rigidness for Visual and Music". Then, I came to the conclusion that the VISUAL MUSIC type work works effectively when creating with the theme of cognition.
