When R. listens to music, his mind generates colours that do not exist in the “real” world as perceived by “normal” people. He perceives classical music as “dark brown”, electronic music as mostly “purple”, and symphonic compositions as “red” (Mila ´n et al., 2007). This is the characteristic of one type of synaestesia.
Syneasthesia is a condition in which stimulation of one sensory modality causes unusual experiences in a second, unstimulated modality.
