TAILIEUCHUNG - Visual Music: Searching for an Aesthetic

The subjects then used an online system to perform the experimental task. A copy of the text specification with the example diagram was placed in front of the computer for easy reference, and the UML experimental diagrams were presented in random order for each subject. The subjects gave a yes/no response to each presented diagram, indicating whether they thought the diagram matched the specification or not: two keys on the keyboard were used for this input. 16 practice diagrams (randomly selected from the 21 experimental diagrams) were presented first. The data from these diagrams was not collected, and the subjects were not aware that these diagrams were not part of the experiment. These. | Visual Music Searching for an Aesthetic Tom DeWitt Abstract-If the nonverbal and emotionally evocative aesthetic of music is to be extended to visual art we must examine the psychology of sight and the intuitive uses of this psychology by visual artists. The structure of the eye the nerve connections between the eye and the brain and the visual cortex can give us clues as to how human perception is uniquely sensitive. These sensitivities amplified through the self-expression of artists can induce emotional responses that are more related to the form of the expression than to the content of the imagery. Works by the author and by other artists who influenced him are used to illustrate these points. I. INTRODUCTION During the nineteenth century Helmholtz 1 studied the relationship between musical harmony and the human perceptual apparatus. His discoveries can guide an investigation into the relationship between music and visual art not because he uncovered a direct correlation but because his method of analysis can be used to find one. In a key finding Helmholtz concluded that we appreciate the geometric progression in sound frequencies because our ears seem to produce these overtones even in the absence of their physical presence. In other words we enjoy the art born from the subtle manipulation of our aural psychology. If we apply this methodology to sight it is reasonable to suggest that the eye has intrinsic physical properties that point toward an aesthetic. The centric structure of the retina with its logarithmic density of sensor cells radiating from the fovia the cone and rod retinal cells that are sensitive respectively to color and monochrome the crossing of left right eye neurons in the optic nerve chiasma and the processing of the visual cortex itself are all unique psychological phenomena that must be examined.
