It was the Victorian polymath Francis Galton (1880) who first reported the condition called Synaesthesia. He noticed that a certain number of people in the general population, who were otherwise completely “normal”, seemed to have a certain peculiarity: they experienced sensations in multiple modalities.For example, musical notes might evoke distinct colours… and colours might in turn be experienced as sounds and rhythms. With a little bit of imagination, we are all capable of “seeing” the harmonies of a piece of music and “listening” to the tonalities of a painting.
