Synesthesia & Creativity: Your Wild Senses Are Up To Something!

Ever thought your senses were messing with you? Not spooky, just… weird. Like a subtle, everyday hallucination? Okay, picture this: you see a jagged, pointy shape and a soft, curvy one. Then, two made-up words pop up – “Bouba” and “Kiki”. Which name goes with which shape? If “Kiki” instantly clicked with the pointy one and “Bouba” with the curvy one, you are hella normal. Almost ninety-five percent of people, no matter their culture or age, do that exact same thing. And this isn’t just a quirky parlor trick. Nope. It’s a big deal for understanding Synesthesia and Creativity.

Bouba/Kiki? Your Brain Just Links Stuff Up

This simple experiment? A German psychologist, Wolfgang Köhler, whipped it up back in 1929. It shows something genuinely profound. Our brains? They make an instant, unconscious connection. Those words themselves are total nonsense in any language. Yet, we link them up.

Why? Folks think our brains match the physical “texture” of the sound to the visual texture of the shape. Say “Bouba,” and your lips round, the sound softens. “Kiki” means sharp tongue movements, a higher pitch in your voice. Your brain mixes a physical feeling with what you see. A real cross-sensory mash-up. You don’t even notice, usually.

Later, neuroscientist V.S. Ramachandran did the same test. Same results everywhere. And another thing: even tiny kids, 2.5 years old, speaking totally different languages, made these identical connections. This isn’t about language learned. Nope. It’s practically hardwired into us.

Synesthesia: When Your Senses Go Wild! Many Artists Get It More

For most of us, these cross-sensory links are quick, quiet moments. But for some, it’s their constant, everyday deal. They experience synesthesia – a brain thing. The fancy Greek words “syn” (together) and “aesthesis” (perception) mean “united senses.” You jab one sense, another one just… goes off.

This isn’t metaphor. Not just poetry. It’s a direct, physical experience. Hear a sound. See a color. Read a letter? Taste something. Look at a number? Feel like it’s got a personality. Over 80 types exist. Chromesthesia is tops (hearing sounds and seeing colors).

Folks guess 2-4% of the general population are synesthetes. But the true number? Probably way higher. A lot of people just figure everyone experiences the world the same way. The big link to creative stuff is particularly strong. Artists, musicians especially, talk about this unique feeling. Singer Alexi Yakam mentioned she thought everyone experienced it. Didn’t realize it was her special thing.

Musicians like Pharrell Williams, for example, can’t make music without seeing colors. He sees seven main colors for musical notes. Chords are mixes; harmonies? Like blends of compatible colors. His group N.E.R.D even named a 2008 album “Seeing Sounds.” For him, it’s not really a talent. More “the only way I understand the world.”

Also Lorde. She said her creative process depends on these sensory experiences. Once, she started a song, and the initial chord progression appeared as a “sickening skin tone.” Gross. But then, as she wrote the pre-chorus and lyrics, the song’s color transformed into “incredible greens.” That saved it from the trash heap. This visual vibe of the music decided if it lived or died. Crazy.

Duke Ellington, the jazz guy? He put it best. For him, the color of a note wasn’t set in stone. It changed based on who played it. Harry Carney’s low C seemed like “dark blue burlap.” But Johnny Hodges’ middle G? “Light blue satin.” The player. The instrument. The performance. All brought unique colors.

Kandinsky & Scriabin: Artists Changed the Game With Their Wild Senses

This crazy way to see the world really pushed some big changes in art history. Picture this: a 30-year-old Russian law professor. He sits in Moscow’s Bolshoi Theatre in 1896, listening to Wagner’s Lohengrin. Suddenly, BOOM! Colors, wild lines, right in front of him! That was Wassily Kandinsky. That night, he abandoned law to become a painter.

Kandinsky’s synesthesia – his experience of sounds as colors, colors as sounds – wasn’t just some weird thing. That became his whole thing, his art ideas. In his 1911 paper Concerning the Spiritual in Art, he wrote, “Color is the keyboard. The eye is the hammer. The soul is the piano with many strings.” For Kandinsky, a painter wasn’t just showing something. They were playing something. And he even called his paintings “Compositions” – a term for both music and art – because for him, painting and composing were basically the same deal.

Way later, almost 100 years, in 2021, Google Arts & Culture, with help from the Centre Pompidou, created an interactive experience based on Kandinsky’s “Yellow-Red-Blue” (1925). By using computers to get his color ideas, they made the painting interactive. Tap yellow? Trumpet blast. Dark blue? A cello plays. So you don’t just see the painting. You play it. Wild.

At the same time, basically, some other Russian guy, composer Alexander Scriabin, went the other way. He tried to turn sound into light. His 1910 work, “Prometheus: The Poem of Fire,” was a massive, 20-minute symphonic poem. But above the regular music notes, he added an extra line. It said “Luce” (Italian for light). A color score. Wild.

Scriabin even wanted a “Clavier à lumières” — a light keyboard that would make the whole concert hall glow with colors changing as music played. A “counterpoint of light.” He never really saw it happen. Some basic light shows happened after he died. It took nearly a century, until 2010, for the Yale University Symphony Orchestra to fully get Scriabin’s 1913 vision with modern technology. Woolsey Hall got colored exactly like he’d seen it. Finally.

So, was Scriabin a real synesthete? People argue. Maybe his color-note stuff was just brainy, from ideas about spirits and light. His friend Rimsky-Korsakov definitely had it. But their color-note plans were totally different. This suggests that the ability to create synesthetic art doesn’t mean you need the brain thing. One might just think up these connections, making them happen on canvas or stage.

Babies: Are They All Synesthetes? Maybe We Just Forget

Perhaps the line between synesthete and non-synesthete is not so clear-cut. A developmental psychologist, Daphne Maurer from McMaster University, stood up in 1993 and asked, “What if babies are all synesthetes?” She looked back at old research, and things started making sense.

A 1974 Harvard Medical School study showed this: you lightly touched a newborn’s wrist? Their touch brain lit up. Expected, right? But then white noise played at the same time, and that activity increased even more. Sound made touch more. Grown-up brains don’t usually do that sound-in-touch thing. But babies did.

Also, a study from the University of Oregon in 1995 found that when 6-month-old babies heard speech, both their hearing and seeing brain parts fired up. They weren’t just hearing it. Kind of like they were seeing the sound. By age three, though? Poof. Gone. Speech was just an ear thing.

What happened between babyhood and age three? Synaptic pruning. The brain starts with a super thick mesh of connections, all the senses blurring together. But as we grow, life and experiences shape the brain, cutting off what’s not used. Eyes for seeing, ears for hearing. Brains get specialized. This pruning ramps up big time between ages seven and nine, making adult brains all neat and separated. So Maurer thinks: synesthetes? Maybe they just don’t trim back as much. Keep some of those intense, baby connections. Not about getting something new. It’s about not losing something old.

This means synesthesia isn’t a brain error. It’s leftover. A piece of a perception we all once had. A baby’s world is a place where senses flow together – sounds touch. Touches color. Colors move. William James called it a “buzzing confusion.” But maybe it’s not confusion at all. Maybe it’s a way richer, more blended feeling. A piece of which some people carry into adulthood.

We All Speak Synesthesia? Our Brains Just Link Stuff Naturally

Even if you’re not a real synesthete, your brain still connects these senses daily. We talk about “warm colors”— but colors aren’t warm. We describe a “sharp sound” – can sound cut? Or a “sweet melody.” A “dark tone.” “Heavy silence.” None of these make logical sense. But we get it. We feel it.

These aren’t just metaphors. Nah. They’re proof our brains built these links between senses. Echoes from our brain’s back alleys. Ramachandran thinks Bouba/Kiki points to how language even started. Where sounds link to shapes, shapes to meaning, meaning to emotion, all through our senses. Language itself is a synesthetic action, really.

So, here’s the real kicker for Synesthesia and Creativity: Creativity? It’s just mashing two separate things together. Color + emotion. Sound + memory. Metaphor + real life. Kandinsky did it on canvas. Ellington with an orchestra. But we do it every day when we feel a movie’s music is “dark,” or a voice “warm,” or a sunset’s “peaceful vibe.”

Research? Says synesthetes are 3-4 times more into art stuff than regular folks. They lean towards creative jobs, spend more time with art. Tests don’t always say they’re “more creative.” But they sure as heck think different. They have wider networks in their head. And they connect crazy different ideas.

Creativity, then, isn’t just knowing stuff. Nope. It’s grabbing two really different things, making them touch. We showed you two shapes, one round, one pointy, and two made-up names. You got it right. Didn’t even think. And that’s ’cause deep down? Your brain still kinda sees sound. Those baby brain traces, where everything talked to everything? Still there, a bit. The real question isn’t “Does sound have color?” it’s “When did we stop seeing them?”

Got Questions? We Got Answers!

Q: What exactly is the Bouba/Kiki thing?
A: It’s a thing where people consistently link weird, made-up words to specific shapes. Like “Kiki” typically goes with a jagged shape, and “Bouba” with a rounded one. Just brain linking senses up (without you knowing).

Q: Is synesthesia super rare?
A: They guess it hits 2-4% of general folks. But this number might be higher because a lot of synesthetes don’t even know their experience is wild, and everyone else gets it too.

Q: How did artists like Kandinsky and Scriabin use this synesthesia in their work?
A: Wassily Kandinsky, a painter, took his sound-as-color, sound-as-line experiences and put ’em right on canvas. Made whole art theories based on it. Alexander Scriabin, a composer, wanted to mix light with music. His music scores had “Luce” (light) notes. He dreamed up a “light keyboard” to flood concert halls with changing colors. But folks still argue if his was internal, or just a really smart idea.
