Synesthesia

Synesthesia (pronounced sin-uhs-thee-zhuh or sin-uhs-zhee-uh)

(1) In neurology and psychology, a neurological or psychological phenomenon in which a particular sensory stimulus triggers a second kind of sensation.

(2) The association of one sensory perception with, or description of it in terms of, another, unlike, perception that is not experienced at the same time.

(3) In literary theory or practice, an artistic device whereby one kind of sensation is described in the terms of another.

(4) In medical diagnostics, where a sensation felt in one part of the body as a result of stimulus that is applied to another, as in referred pain.

1881: From the Modern French or the New Latin and derived from Ancient Greek σύν (sún (with) or syn (together) + αἴσθησις (aísthēsis), (sensation; feeling) from the primitive Indo-European root au (to perceive) + abstract noun suffix -ia.  The word was modelled after existing construction anaesthesia.  Traditional spelling in the British Empire was synæsthesia but the US form synesthesia appears now global.  The meaning in psychology relating to the senses (colors that seem to the perceiver to having odor, etc.) is from 1891.  Synesthesia & synaesthete are nouns, synaesthetic is an adjective and synesthetically is an adverb; the noun plural is synesthesias..

Clinicians have two categories of synesthesia: projective and associative.  Those who project see actual colours or shapes when stimulated whereas associators will feel an involuntary connection between the stimulus and the sense that it triggers.  For example, in the form chromesthesia synesthesia (sound to color) a projector would listen to a piano and see a purple shape whereas an associator might respond to the music by thinking it “sounds” purple.  There are a number of types of synesthesia, the best known of which grapheme-color synesthesia or the association of colours with letters or words.  In auditory-tactile synesthesia, certain sounds can induce sensations in parts of the body and debate continues about whether the near-universal reaction(s) induced by finger nails on a blackboard indicates synesthesia is a spectrum condition or this example is endemic in human physiology.   Lexical-gustatory synesthesia is the phenomenon of certain tastes being experienced upon hearing certain words.  Mirror-touch synesthesia is where someone feels the same sensation another person feels such as when a synesthete sees another touched on the arm; the synesthete involuntarily feeling a touch in the same place.  Logically, every possible combination of experiences which can occur can be a type of synesthesia.  Something need not be wide-spread to be a type of synesthesia, it needs just to be specific.

In Russian painter and art theorist Wassily Kandinsky’s (1866–1944) particular synesthesia, color and music inextricably were tangled and so precise was it that he associated each note with an exact hue and it was so intrinsic to his being that he once observed: “…the sound of colors is so definite that it would be hard to find anyone who would express bright yellow with bass notes or dark lake with treble.”  It meant his experience of music was heightened, indeed defined, by the range of visual perceptions which shifted with every note.  The music of Richard Wagner (1813–1883) has had its consequences, good and bad, and it was his vivid visual response to a performance of Wagner’s Lohengrin (1850) at Moscow’s Bolshoi Theatre that he abandoned his successful career as a lawyer and devoted himself to the painting which had been his hobby.  Accepted as a student at Munich’s Academy of Fine Arts, he later described the Wagnerian transformation of his life: “I saw all my colors in spirit, before my eyes. Wild, almost crazy lines were sketched in front of me.”  Wagner has led a few astray but he took Kandinsky on a good path; the world needs more artists more than it needs more lawyers.

Music remained critical to the development of Kandinsky’s abstract paintings and noting the way the Viennese composer Arnold Schoenberg (1874–1951) had abandoned tonal and harmonic conventions in his compositions, he rejected the figure or recognizable object in favor of shapes, lines, and discordant colors which he deployed overlaid on texture to create a rhythmic visual experience which as closely as possible emulated in a two-dimensional space the emotional response he’d experienced when hearing the sounds.  Unsurprisingly, Kandinsky gave many of his paintings musical titles, such as Composition or Improvisation and it wasn’t unusual for critics to use phrases like “Kandinsky’s symphony of colors”.

Kandinsky also perceived color also had the ability to touch the feelings of the viewers, yellow able to disturb while blue awakened the highest spiritual aspirations.  That may have been mapping his experience as a synaesthete on to those not able to enjoy the gift but it was certainly an insight into his visions.  In 1911, Kandinsky published Über das Geistige in der Kunst (Concerning the Spiritual in Art) in which he defined the three types of painting: impressions, improvisations and compositions.  Impressions were based on an external reality while improvisations and compositions depicted images summoned from the unconscious, compositions the more formal of the two.  The treatise is one of the landmarks in the theoretical foundations of abstraction and remains an important contribution to an explanation of the techniques with which art can be constructed in an attempt to evoke psychological, physical, and emotional responses.
