A research group led by Assistant Professor Kosuke Ito of the University of Niigata Brain Research Institute's Integrated Brain Function Research Center is a common pattern of colors felt by sounds, which is the phenomenon of the brain that feels colors when listening to sounds and music. He revealed the hidden rule that the seven sounds and the seven colors of the rainbow correspond in order.
"Synesthesia" is a phenomenon in the brain that feels color when listening to sounds and music.Among musicians such as Hungarian pianist and composer Franz Liszt, Russian composer Limsky-Korsakov, Finnish composer Jean Sibelius, American guitarist Edward Van Halen, and Japanese conductor Hiroshi Sato. There are relatively many people who have this "sympathy".
However, as for tonal colors such as D major, as Liszt and Limsky-Korsakov disagree, there are large individual differences in the sense of color, and there is no fixed rule for the correspondence between sound and color. Has been thought.
However, previous studies have only sporadically targeted a small number of synesthesia and have not been fully investigated.Therefore, as a result of gathering a large number of 15 synesthesia people and examining them in detail this time, when we asked the synesthesia people to freely choose the color that they felt in the sound, although there were individual differences, the average value of the selected color was obtained. If you calculate and search for the pattern that is common to the background, the hidden law that the seven sounds of Doremi Fasorashi and the seven colors of the rainbow correspond in order, such as red for do, yellow for le, green for mi, blue for so, and purple for shi. Became clear.
Furthermore, upon closer examination in psychological experiments, it was found that color is not associated with the sound itself, but with the name of the sound (floor name), but it is unknown why such a connection occurs. It is possible that the cause is the "Doremi song" that everyone knows, such as "Re is a lemon" and "So is a blue sky", but in that case, the part that cannot be explained, such as the red of the do and the purple of the shi. Will remain.
It is hoped that the investigation of this phenomenon will be a hint to solve the unexplained problem of why and how our brains are moved by music.
