The forgotten symphony: When colour became music

Yet today, who remembers those canvases where violet-blue swirls like a waltz, where orange and green clash in a chromatic duel? Who knows of these two Americans who, even before Europe dominated abstraction, invented a visual language where each hue became a note, each composition a melody? Their story is one of audacity too soon forgotten, of a science of colour ahead of its time, of a synesthetic dream that continues to haunt artists' studios today.

01The studio where light became matter

Picture a cramped space, bathed in golden light filtering through grimy windows. On the walls, oil studies hang beside Wagner scores and Japanese prints. In the centre, a blank canvas waits, like a blank page before the first note. Macdonald-Wright and Russell lay down their brushes with the precision of surgeons. No subject, no landscape, no portrait. Just forms that emerge and vanish beneath their fingers, guided by a single law: that of chromatic harmony.

Their method? A blend of scientific madness and near-mystical intuition. They had read Chevreul, the French chemist who revolutionised the textile industry by studying simultaneous contrasts. They had pored over Rood’s optics treatises, where colour became a mathematical equation. But above all, they had listened. To Debussy, of course, but also to Scriabin, the Russian composer who saw colours when he heard sounds. "Why can’t painting be as immediate as music?" Macdonald-Wright murmurs as he applies a stroke of vermilion next to Prussian blue. "Why must we always represent something when we can make people feel?"

On the canvas, the colours do not blend. They coexist, respond to one another, oppose. A vivid red sits beside emerald green, creating a vibration almost unbearable to the eye. A lemon yellow dances with deep violet, like two lovers drawn together and pushed apart. "Look," Russell says, stepping back. "The green seems more intense beside the red. That’s the magic of simultaneous contrast." Macdonald-Wright smiles. "No—it’s magic, full stop."

02The war of colours: when America discovered abstraction

The Salon des Indépendants in Paris. Their canvases, exhibited alongside those of Delaunay, provoke a minor earthquake in the art world. Apollinaire, ever on the lookout for revolutions, exclaims: "At last, an abstraction with breath!" Yet behind the praise, a question lingers: were these Americans merely followers, epigones of French Orphism?.

The answer would come from New York, a year later. The Armory Show had shaken America with its Demoiselles d’Avignon and Nude Descending a Staircase. But in a corner of the gallery, almost unnoticed, Macdonald-Wright and Russell’s canvases unfurled their colours like flags of a new era. "It’s decoration!" sneered a critic from the New York Tribune. "Tapestry for millionaires!" another chimed in. Yet in the shadows, a few discerning collectors began to take notice of these strange chromatic symphonies.

Among them was Walter Arensberg, the eccentric patron who collected Duchamps and African masks with equal fervour. He bought Synchromy in Orange: To Form for a pittance, unaware that the canvas would one day become a jewel of the Philadelphia Museum of Art. "These boys have something," he confided to his wife. "They’re not painting objects. They’re painting space itself."

Yet war broke out. Russell, the more pragmatic of the two, returned to the United States and tried to convince a sceptical public. Macdonald-Wright stayed in Paris until 1914, before fleeing a Europe in flames. Their movement, born in the effervescence of Parisian cafés, would now have to face the scepticism of a country unprepared for abstraction.

03The secret code of colours: a score for the eyes

If you look closely at Synchromy in Blue-Violet, you’ll notice something strange. The forms represent nothing, and yet they seem to move. The blue-violet swirls like smoke, the lemon yellow bursts like a sun. Macdonald-Wright once explained that this canvas was "a fugue for the eyes." But how can a painting be a fugue?

The answer lies in their system, which they called "the chromatic keyboard." Each colour corresponded to a note, each shade to a pitch. Red? A C. Orange? A D. Yellow? An E. By layering these hues according to precise rules, they created "visual chords," combinations that resonated in the eye like musical harmonies in the ear.

Russell took the analogy further. His canvases, like Synchromy in Orange: To Form, resembled musical scores. Geometric forms interlock like notes on a staff. Warm colours (red, orange) rise, while cool ones (blue, violet) descend. "A Synchromist painting must be read like a score," he wrote in a letter to Arensberg. "From left to right, from low to high."

But their true genius lay in what they called "optical mixing." Instead of blending colours on the palette, they juxtaposed them on the canvas, letting the viewer’s eye do the work. A red dot beside a green one? The eye perceives yellow. A touch of blue next to yellow? Green emerges. It was the same technique Seurat used in his pointillist works, but applied to pure abstraction. "We don’t paint colours," Macdonald-Wright explained. "We paint light itself."

04The Russell enigma: the genius who abandoned abstraction

Morgan Russell sets down his brush and looks at his latest Synchromist canvas. Synchromy in Green and Orange is finished. A strange work, almost hybrid, where abstract forms seem on the verge of becoming something figurative. "It’s over," he murmurs. "Abstraction has reached its limits.".

No one quite understands what’s happening. Russell, one of the pioneers of non-figurative art, turns his back on his own movement. In the years that follow, he returns to more traditional subjects: nudes, landscapes, still lifes. His colours grow darker, almost melancholic. "I no longer believe painting should be pure," he confides to a friend. "It has to tell a story. Otherwise, what’s the point?"

Art historians have debated the reasons ever since. Some see the failure of a man who never found his audience. Others, like Robert Storr, read it as a form of courage: "Russell understood before anyone else that abstraction wasn’t an end in itself, but a tool. When he felt it no longer served him, he abandoned it. That’s true artistic integrity."

Yet in his notebooks, sketches tell another story. Studies for canvases that were never realised, where abstract forms brush against human silhouettes. As if he had tried, to the very end, to reconcile the two worlds. As if he had searched, in vain, for a third way.

05The ghosts of colour: what synchronism left behind

If you walk into a contemporary art gallery today, you might encounter works that feel strangely familiar. Those vast colour fields by Mark Rothko? Those optical vibrations by Bridget Riley? Those light plays by James Turrell? All owe something to Macdonald-Wright and Russell, even if they don’t know it.

Take Rothko’s Orange and Yellow. At first glance, nothing to do with Synchromist canvases. Yet look closer. The way the yellow seems to radiate from the centre, like a light source. The way the orange and yellow converse, creating a tension almost musical. "Rothko took what we started further," Macdonald-Wright would later acknowledge. "He removed the forms, kept the colours, and turned painting into an almost mystical experience."

The same goes for the Op Art of the 1960s. The optical illusions of Victor Vasarely, the hypnotic patterns of Bridget Riley? All rest on the Synchromist principle of simultaneous contrast. "They turned our science into spectacle," Riley once said. "But without them, we wouldn’t exist."

Yet synchronism’s most beautiful legacy may not be in museums, but in the studio of every artist who has ever dreamed of making colours sing. In that revolutionary idea, back in 1913, that painting could be something other than a representation of the world. That it could be a sensory experience, pure emotion, a silent symphony.

06The ghost studio: where colour still dances

Stanton Macdonald-Wright, 83 years old, dies in his home in Pacific Palisades. In his studio, unfinished canvases still wait. Some are chromatic symphonies, others abstract landscapes inspired by Japanese art. On an easel, a study for a mural that was never realised. "Colour is a universal language," he had written decades earlier. "It speaks to the soul without words.".

Today, if you visit the MoMA, you’ll find Synchromy in Blue-Violet hanging in a room dedicated to abstraction. Visitors often walk past without stopping, without seeing the revolution hidden there. Yet if you step closer, if you let your eyes adjust to the dance of colours, you might hear something. A distant melody, like an echo of Debussy. A vibration, as if the canvas were breathing.

That is the true mystery of synchronism. These canvases are not objects. They are experiences. Suspended moments where colour becomes music, where light becomes emotion. And if you listen closely, you might hear, in the silence of the museum, the laughter of two young Americans who, one evening in 1912, dared to believe that art could be something other than an imitation of reality.

A symphony.
