Directed Research Report on Synesthesia, Art and Media
Background
Synesthesia (sin-əs-THEE-sha) is a neurological condition in which one
sensory function can simultaneously and inadvertently trigger other sensory
functions. A synesthete, or a person who has synesthetic experiences on a regular
basis, can experience taste from sounds, color from words and letters, and physical
feeling from visual stimuli, among other possible combinations. This report on my
research will discuss some background on synesthesia before focusing on the
artistic implications of synesthesia, and will end on my own composition, Chroma
Improv, that was inspired by synesthetic works.
Despite historic skepticism, synesthesia is a real, diagnosable condition in
one in about two thousand adults.1 It is much more common in adult females than
adult males, by about a six to one ratio.2 Many neurologists who have studied
synesthesia believe that all, or many, children are born synesthetic and gradually
lose it as they get older.3 Formal research studies on synesthesia began with
Richard Cytowic in the 1980s, and modern research using brain imaging
technology gives little doubt that the condition is very real for synesthetes.4

Cytowic’s five criteria for diagnosing synesthesia have remained as the
standard. The five criteria are:
1) it must be involuntary,
2) the synesthete realizes that the experiences are not happening in reality,
3) the experiences must be long-term, consistent, and simple in correlation,
4) the synesthete must be able to remember and recall the experiences, and
5) the experiences must be emotional.5
This differentiates from a multisensory experience in a few ways: a multisensory
experience can be voluntary, it can be substantiated in reality, it can happen as
many times as the experience occurs, and the experience does not need to be either
memorable or emotional.
Perhaps one in two thousand sounds like a very rare condition not worthy of
research, but in reality, even if a person is not a diagnosable synesthete, it does not
invalidate the possibility of synesthetic experiences. Some studies suggest that
about one in twenty-three people have had memorable synesthetic experiences.6
And, a 2006 study reported in Discover magazine found that given a choice
between animations made by synesthetes and non-synesthetes, most people found
the animations created by synesthetes were better synchronized. This means that
even regular people can link different senses unknowingly, a view also held by
Cytowic.7

Perhaps then, synesthetic experiences can be induced or learned by non-
synesthetes. Researchers are looking into several avenues for inducing or learning
synesthesia. Examples of this are through odor-taste synesthesia, which seems to
be the most natural form of it,8 drugs like cannabis and opiates, and in particular
LSD,9 certain forms of mediation,10 and more extreme methods including sensory
deprivation, where having one sense shut off incurs synesthetic experiences,
epilepsy, and electrical stimulation of the brain.11 All of these forms, to varying
degrees, have been found to induce synesthetic experiences in non-synesthetic
people. Also, researchers have found a person’s quality of vision can be
dramatically altered in quality by what they hear, as well as the interpretation of
visual events and motion especially in terms of time.12
There are three traditional, and four more modern, theories about
understanding how synesthesia works. The three traditional theories are miswiring,
leakage, and wrong feedback; the more modern views are via the limbic system,
neonatal pruning, which means everyone has it and loses it as we get older, brain
plasticity, which uses the argument that the fact the brain can replicate lost
functions may explain synesthesia, and disinhibition.13 Richard Cytowic, one of the

leading researchers on synesthesia, says synesthetic experiences look similar
physically to migraines, in which sensory distortion causes disconnect between
different brain functions.14 Cytowic believes more so in the more modern theories
of synesthesia, particularly in neonatal pruning, writing that the condition exists in
other primates and calling synesthetes simply ‘more aware’ than the general
population.15
The focus of my research is not on the neurological or psychological
research of synesthesia. Rather, it is about the artistic and media implications of
synesthesia. It is also about the artists, both synesthetes and non-synesthetes, who
have created works that explore the synesthetic phenomenon.
Common Ground
It is important to recognize when discussing synesthetic artists is that all
synesthetes have unique correlations between the senses, no two synesthetes are
the same.16 When discussing specific artists later on in this report, I will go into
detail on their own connections, but first I would like to discuss the similarities, to
establish common ground between synesthetic artists.
Influences on synesthetes are both external and internal. And with
imagination and creativity being linked together, and synesthetes being seen as
imaginative by the general population’s standards, synesthetes are viewed as

creative people.17 Many synesthetes are closeted, or were at some time, and find
hostility when describing their experiences, which also shows up in synesthetic
work.18
Internal influences are perhaps even more significant however. Research has
found that, for most synesthetes, color is what is triggered by other senses, making
it the dominate synesthetic response. Taste and sound as a response are also not
uncommon.19 Research has also found that when synesthetes experience conflict
between their own internal correspondences and what they literally experiencing, it
causes distress in the synesthete.20 Unpleasant color combinations can trigger
negative synesthetic experiences.21 Extremity in general has an interesting effect
on synesthetes. Large literal changes can cause even greater changes in perception,
leading to the idea that synesthesia is effected by context.22 Loud or extreme
sensory information can also blur for synesthetes whether or not the synesthetic
experience is real.23

There are some interesting observations made about synesthetic work, of
course these are all generalizations. Synesthetes tend to prefer soft to well defined
shapes,24 and prefer to keep their work simple as opposed to complex, using black
or white backgrounds, keeping their source material restricted to a smaller amount,
and the end result is typically more asymmetrical.25 Finally, linguistics may
influence synesthetic perception as well, for example the phrase ‘red hot.’26
Again, all synesthetes are unique in their correspondences between senses.
However, there are some things that are common in association. Lighter colors are
associated with higher pitch, darker colors are associated with lower pitch.27 The
vowels ‘u’ and ‘o’ are darker, ‘a’ in the middle, and ‘e’ and ‘i’ are typically lighter
in color.28 Another way of associating pitch with color: colors tend to start at red on
the note ‘C’ and move through the color wheel until green at the note ‘G’, and are
shades of pink and purple thereafter.29 Matching qualities are bright, smooth, hard,
cold, and sharp; another set is dull, rough, soft, blunt, warm, and heavy.30

Perhaps a connection between synesthesia and the general population is the
use of ratios in media and art. From Cytowic’s earlier book: design principles, like
the divine proportion and thirds, as well as musical temperaments, were not forced
but developed intuitively. Earlier societies gave shapes specific color
correspondences, like yellow triangles, blue circles, or red squares, and these
combinations are also seen in renaissance artwork. Ratios and numbers are
associated with particular shapes, like multiples of three for triangles and the
pattern 2, 4, 16... for squares. These ratios across perceptual boundaries have
actually been found to be similar in correspondence for synesthetes.31
With that, let’s move on to synesthetic artists and the artwork that has been
make in the name of synesthesia.
Artistic Synesthetes and Synesthetic Art
Prometheus: Poem of Fire (1910), a symphonic poem by Alexander
Scriabin, is one of the most famous synesthetic works. Prometheus is about twenty
minutes in length, and is the story of an early man stealing fire from the gods. It
makes use of a color organ which outputs both music and colored light in specified
shapes.32 The instrument did not exist at the time the work was composed.33
Scriabin articulated in the score how the colors and shapes corresponded with the
music. The colors and shapes correspond with musical keys and not by note,

moving around the circle of fifths,34 leading some to call Scriabin not a true
synesthete.35 Regardless of that, the mapping Scriabin developed is then used to
tell the story of Prometheus, with red signifying fire, blue signifying the gods, and
so forth. Perhaps the most significant output of the symphonic poem is the mystic
chord, sometimes called the Prometheus chord, that Scriabin used as a foundational
structure of Prometheus and at pivotal moments directly composed four times in
the work.36 The six note chord is based on a pattern of fourths. While dissonant, it
sounds familiar and comforting.
Die glückliche Hand, an opera by Arnold Schoenberg was composed
1910-1913, and like Prometheus approximately twenty minutes in length. It is the
story of love lost, and infuses themes of artistic criticism and repetition of
mistakes. Schoenberg uses colors of lights, costumes, and set pieces to synchronize
with the onstage personalities and the plot, using conventions as opposed to
internalized synesthesia. The greatest example of synesthesia in Die gluckliche
Hand is known as the color crescendo, appearing in the third of five scenes. This
dramatic short sequence rapidly integrates the precedences in color-sound
correspondence earlier in the opera, and also synchronizes with the rapid changes

in emotion of the main character. It serves as a powerful transition in the outlook of
the main character in the story.37
Schoenberg was a member of the artistic group Der Blaue Reiter (The Blue
Rider), which had at least one truly synesthetic member. Wassily Kandinsky saw
deep rooted connections between all the senses and was inspired a variety of
sensory information, which he translated into paint. His most famous synesthetic
work is call Der gelbe Klang or The Yellow Sound (1912), a theater work involving
several other types of artists, where Kandinsky correlates watercolor painting,
lighting, movement on film, dance, and music.38
Chronochromie, Des Canyons aux Etoiles and Couleurs de la Cité Céleste
are examples of orchestral music by the sound-color synesthete Oliver Messiaen
(composed 1929 to 1974) that had synesthetic influences. The works are not mixed
media, they are only music. Messiaen’s sound-color synesthesia is not as well
documented as other composers, but certainly made references to them throughout
his works.39 Messiaen was largely a twelve tone composer, and so analyzing his
synesthetic experiences from it is complex.40 His music has been found to link
chord spacing and absolute pitch with color.41 The very form of the three works

listed above is based on color.42 Messiaen did not use lighting or other techniques
to demonstrate his perception of the generated colors, but they are still useful to
look at as they influence his music. While Messiaen’s sound-color correspondences
have been found to not be one hundred percent consistent,43 they are still a
valuable tool for analyzing his music.
Michael Torke is a living synesthetic composer who primarily composes
orchestral works. He primarily associates colors with key signatures and notes in
the context of their key signature.44 His most famous synesthetic composition is
Ecstatic Orange, and his other synesthesia inspired works include Green, Purple,
Ash, and Bright Blue Music. All of these works have dance choreographed to them
as well.45 Torke interprets these works as dreams in particular colors, exploring the
possibilities within each of the colors.46
Another more current example of synesthesia in artwork is the video game
Rez. In Rez, as the player interacts with the very abstract and colorful game
environment by shooting enemies and objects, different sounds are generated along
with various colors and shapes. The designers and artists behind Rez cite
Kandinsky’s paintings as inspiration for creating the game.47

There are many other examples of synesthesia in art and media, including
works by electroacoustic composer Edgard Varese, painters Kurt Schwitters, Piet
Mondrian, and David Hockney, and the films Fantasia and Dog Star Man. There is
also an entire movement in video art called Visual Music, which I cannot even
begin to list the number of works created as part of it.
Creating Synesthetic Experiences
All of this leads to the question: how would one create a synesthetic piece of
art or media? The most obvious is to use the diagnosis of synesthesia as a guide
and from what I have written about influences and similarities:
• keeping it simple in correlation,
• keeping it consistent in correlation,
• emphasizing colors and words,
• combining multiple senses,
• limiting source material,
• blurring extremities,
• and using ratios to create the correlations between senses
would all make sense. But perhaps there is more we can do, more we can use from
synesthesia in art and in media.
The academic journal Leonardo had a series of articles about synesthesia
and art in the late eighties and early nineties. One article described the
requirements of the ultimate synesthetic medium: it does a wide variety of
mediums, it is spatial oriented, it has an organizational system to keep everything
Heis, Synesthesia, Art and Media 11
connected, and it takes full advantage of ability to “capture, generate, process and
spatially manipulate” the source material.48
The book Analysing Musical Multimedia is a treasure of knowledge about
mixed media aesthetics, and particularly strong at connecting them to synesthesia.
The basic question to ask, according to the book, is not to ask what a medium has
or is, but what it does to the other mediums involved. This implies making
connections between mediums, and to hide the synchronization between mediums,
using things like movement, color, shape, and emotion. One medium can
significantly alter the time perception of others; particularly in the case of sound,
which tends to be more abstract, on visual, which tends to be more literal.
Metaphors are one of the best models for multimedia, using compliments instead
of contrast, limiting the use of contrast for emphasis.49 Simply connecting
mediums is not synesthetic in and of itself, but the idea that multisensory aesthetics
are rooted in synesthesia is a powerful one.
Chroma Improv
My composition, Chroma Improv, while I do not consider it a truly
synesthetic work, it is inspired by synesthesia and previous work done by
synesthetic artists. My focus of the piece is on the relationship between color and
sound, and sound in the form of musical sonorities. The piece, as indicated in the
title, is an improvisational piece of approximately three to ten minutes. This

improvisation functions similar to the way a true synesthete would perceive color
and sound fusion: on the fly.
I do not consider this to be a synesthetic work because the multi-sensory
experience is forced onto the audience rather than being internal. The video part is
an attempt to create what a synesthete might perceive visually when hearing the
sonorities generated by the computer, an aid for non-synesthetes to understand the
concept.
The setup of the work involves an electric bass player, standing in front of a
projected screen, and a camera positioned to view the the front of the bass player.
The score is set up in a six by six grid of twelve preselected pitches, with register
preselected, and the bass player improvises by moving across the grid in various
directions with no predetermined rhythm, volume, articulation, or tempo. As the
bass player plays specific notes, the computer categorizes the pitch though a pitch
recognition algorithm as one of twelve pitches.
The computer then, based on which pitch is currently being played, outputs
data for both sound and video. For the sound part, the computer transposes the
incoming signal three to six discreet times. It then pulses out the transposed signals
individually at a rate determined by which pitch is being performed by the bass
player, and each transposed pitch has its own unique pulse rate. This is in addition
to outputting the dry bass signal for reference. Perhaps a future version of this
work will also use sound filtering to change the timbre of the sound output on the
basis of the incoming pitch as well.
For the video part, red, green, and blue values on a scale from zero to two
hundred fifty-five have been preselected for each one of the twelve possible
Heis, Synesthesia, Art and Media 13
pitches, and on the basis of which pitch is currently being played the computer
filters out the color of the video signal from the camera on the bass player and
outputs the video signal onto the projector.
While this seemingly simple concept that synchronizes sonority, pulse rates,
and video color may seem too basic to be an interesting composition, it is true to
the concept of the work. The end result is more than the sum of its parts, which
only aids to prove that synesthesia is something we all experience at varying
degrees.
The future, conclusions
Synesthesia will grow as an area of interest as our world accelerates towards
combining senses for entertainment, for education, and for information. Things like
motion sensors, virtual reality, and feedback systems are all on the rise in many
different mediums, like films, games, and interactive works. It is possible that
because of this, the number of cases of diagnosable synesthesia will increase. The
more we understand this unique combination of the senses, the better we can craft
mixed media messages and artwork to generate the maximum response in the
audience.
