Four Notes and a Nation

The tiny jingle that brought a rock legend to a standstill on a platform, and then landed everyone in court

You know it the moment you hear it.

Do. Sol. La. Mi.

Four notes. Less than three seconds. And yet, if you have ever stood on a platform in a French train station, waiting for an announcement about your train, your delayed train, your train that has inexplicably decided to go somewhere else entirely, those four notes are already inside you. They are the sound of France in transit. The sound of attends (wait). The sound of something about to happen.

I was listening to a BBC4 programme recently about the man who made them, and I have been thinking about it ever since. Because the story of those four notes turns out to be one of the more extraordinary tales in French cultural life. It involves a sound designer, a railway company willing to back him, two anonymous female singers who have kept their secret for twenty years, a rock legend holding his iPhone up to a train station speaker, a houseboat studio on the Thames, and eventually, inevitably, a lawsuit in Paris. Not bad for three seconds of audio.

The brief: give France’s railway a sound people will feel something about

The man at the centre of the story is Michaël Boumendil, founder of a Paris-based sound branding agency called Sixième Son. In 2004, the SNCF came to him with a problem. The SNCF had always used a jingle, but it was the old one, the Do-Me-Sol of the 1990s, and it had gone stale. The company was going through a full rebrand, new logo and all, and the sonic identity needed to keep pace. Boumendil’s brief was simple: give France’s national railway a sound that people would actually feel something about.

Before a single note was composed, Sixième Son did something quite unusual. According to The Beauty of Transport, the agency put SNCF’s own officials through a kind of mental retraining, pushing them to think about ‘identity’ rather than music. What does this company stand for? What should it feel like to travel with us? Only once those questions had been answered did the composition begin.

Boumendil later told Canal+ that what he wanted was simplicity: “four notes, with a rather feminine voice, would make a strong impression.” He was reportedly inspired by a Calogero song, “En apesanteur,” which means weightlessness, and has a floating, suspended quality to it. You can hear that in the final result, if you listen for it. There is something unresolved about those four notes, something that leans forward, that makes you pay attention. Which is, of course, exactly the point.

The notes were recorded using two female voices. To this day, nobody knows who those women are. They chose anonymity from the start, and in twenty years neither has ever come forward. Which, if you think about it, is its own kind of discipline.

The new jingle launched on 15 March 2005. France simply took it in, without fanfare, without fuss. It became, very quickly, part of the furniture of daily life.

“One of the successes of this sound DNA is, without a doubt, the power of what we created together with Sixieme Son. Today, everybody recognises those 4 little notes and knows automatically that we are speaking about SNCF. It says who we are and what we stand for.” Patrick Ropert MD Gare & Connections, SNCF

One decision, no focus groups, and a man willing to carry the can

What most people don’t know is how close it came to never happening. The man who brought Boumendil in was Bernard Emsellem, SNCF’s director of communications, and the decision of what to do with Boumendil’s proposal rested entirely with him. He realised that something this innovative would almost certainly be killed by a focus group. The rail industry is conservative by nature, and asking a room full of people whether they’d like to replace a familiar chime with a human voice singing four notes in a minor key was unlikely to produce a standing ovation.

So Emsellem simply decided. No user testing, no research on acceptability, no committee. Just a single person putting himself out on a limb, knowing that if it went wrong, he would be carrying the can entirely alone. As The Beauty of Transport puts it, sometimes you have to lead opinion, not follow it.

It did not go wrong.

The almost absurd numbers

Here is what twenty years of four notes will do for you. According to Sixième Son’s own research, 98% of French people recognise the SNCF jingle. Ninety-four per cent associate it correctly with the brand. Eighty-one per cent say they feel genuinely ‘attached’ to it. Attached. To a train station sound logo.

It plays between 100,000 and 150,000 times a day, roughly 2.3 times per second, somewhere in France, right now as you read this. Do. Sol. La. Mi. It has been updated three times (in 2005, 2009 and 2013), each time modernising the production while leaving those four notes completely intact. It has won more sonic branding awards than any other sound identity in the world. It is, by any measure, the most recognised piece of French audio that isn’t the Marseillaise.

The numbers are just the beginning.
Behind the paywall: the Pink Floyd guitarist who heard those four notes at a provincial train station and held his iPhone up to the speaker, the lawsuit that followed across three French courts over six years, the woman who has been the voice of the SNCF since 1981 and once quietly rewrote an announcement because it made no grammatical sense, and what those four notes are actually doing, musically, that makes them so distinctly and irreducibly French.
