The structures of musical scores and sentences are similar to each other. In both cases the individual symbols, such as musical tones, rests, letters and so on, make up groups, namely phrases and words. Musical scores consist of phrases and sentences consist of words. The purpose of this paper is to clarify the human visual information capacity for musical tones and to compare it with that for letters. The eye movements of the participants were measured by the eye movement measuring system, Talk Eye. By analysing the fixation points, the visual information capacities were obtained. It was found that at a single glance about 1 musical tone was recognized when a series of musical tones in random order was shown. The capacity for a musical score was about 3 symbols. For a series of random characters about 2 symbols and for sentences more than 8 symbols were recognized. In terms of information value, about 6.5 bits of visual information were percieved from a series of random musical tones. From a musical score, about 19 bits of information were perceived. On the other hand, when a series of random characters was shown, about 11 bits of information were perceived, and when sentences were shown, about 62 bits were perceived.
