How Music Boxes Work: The Tiny Machines That Played Music Before Records.

Pins, gears, and a comb of steel teeth: the story of the music box, from a Geneva watchmaker's bench to a New Jersey factory floor.

By J.J. Dakota

Wind a music box, and before a single note sounds you can feel it: a small, tight resistance under your fingers as the spring takes up the tension. Then you let go, something inside begins to turn, and a tune comes out of a wooden box as if it had been waiting there all along.

Now that music lives in our pockets, it's easy to forget how strange that once was. For most of human history, if you wanted to hear music, somebody in the room had to play it. The music box changed that. For roughly a century, before the phonograph and the radio took over, these little machines were how ordinary families brought music home and kept it.

A bell tower in a snuffbox

The story usually begins in Geneva in 1796, with a watchmaker named Antoine Favre. Clockmakers had long built carillons, sets of tuned bells struck by tiny hammers, into clocks and watches, but bells are bulky and fragile. Favre's idea was to replace them with thin blades of tuned steel plucked directly by pins on a turning cylinder. He presented it to Geneva's Société des Arts as a "carillon without bells," small enough to fit inside an ordinary snuffbox.

It transformed the Geneva watch trade. It did not transform Favre's fortunes. By 1799 he was losing his eyesight and had to ask the same society for a small loan, while other makers built thriving businesses on his idea. He may not even have been the first: a Frenchman had shown tuned vibrating blades to the French Academy of Sciences back in 1769. Inventions, like tunes, have a way of being found twice.

How the machine actually works

Every classic music box, from a pocket trinket to a parlor cabinet, runs on the same few parts.

The voice is the comb: a single plate of hardened steel cut into a row of teeth, long ones for the low notes and short ones for the high, each tuned to its pitch. The score is the cylinder, a brass drum studded with hundreds or even thousands of tiny steel pins. As the cylinder turns, each pin catches a tooth, lifts it, and lets it go, and the tooth rings. Every pin is one note at one moment in the tune, and every one of them was set by hand.

A wound spring supplies the power, and a small spinning fan called the governor keeps the tempo steady, catching the air like a pinwheel so the tune doesn't race. Finer boxes added refinements: tiny dampers to quiet a tooth just before it's plucked again, and sometimes drums, bells, or reeds hidden inside the case.

That's the whole trick. Pins, teeth, a spring, and time.

The mountains that made music

At first these movements were tucked inside watches, snuffboxes, and other small luxuries, and travelers carried them home as souvenirs of Switzerland. Around 1815 the movements grew large enough to become an industry of their own, separate from watchmaking. Geneva's production peaked around 1860 at an estimated 13,000 pieces, employing more than a thousand people.

High in the Jura mountains, the village of Sainte-Croix took up the craft around 1811 and by the end of the century had become a world center of music box making. It's a lovely example of how skill outlives the product it was built for: the same precision know-how later produced Bolex film cameras and Hermes typewriters in the same remote town. Sainte-Croix still has its music box museum, and the craft has never entirely left.

The problem with cylinders, and the disc that solved it

A cylinder box had one great weakness. Its tunes were pinned into it forever. A box might play six or eight airs, but when you tired of them, that was that.

In 1885 in Leipzig, Paul Lochmann patented a solution: a flat metal disc with projections stamped into it, which could be lifted off and swapped for another, very much like a record. His company, Symphonion, produced the first disc-playing music box. Discs could be made cheaply by the thousand, so a family could buy one machine and keep adding music to it for years. Disc boxes rarely matched the fine Swiss cylinder boxes for tone, but they won on price and choice, and Leipzig makers exported several hundred thousand of them around the world.

Some of them went to work in public. Around 1889, a bookshop in Melbourne, Australia, ordered a Symphonion more than seven feet tall that played a tune whenever a customer dropped a penny into the slot. It was, in every way that matters, an ancestor of the jukebox.

The Regina, and a very strange ending

One of Lochmann's early partners, Gustave Brachhausen, left to help found a rival firm, Polyphon, and in 1892 sailed to America to start another. His Regina Music Box Company settled in Rahway, New Jersey, and became the best-known American maker, building everything from small table boxes to tall, coin-operated machines for shops and saloons. Regina understood the beauty of a product that kept earning after the sale: every box owner was a customer for new discs. One of its turn-of-the-century advertisements promised a box that was "a dispeller of gloom, a bringer of happiness."

Then the phonograph grew up. A machine that could play a real orchestra, or a real human voice, was hard to compete with, and by the early 1900s the music box business was in trouble. Regina did what struggling companies do: it diversified. In 1902 it dropped "Music Box" from its name and began trying other products, from player pianos to office copying presses. One of those experiments was a hand-pumped vacuum cleaner.

The vacuum cleaners outlasted everything else. For most of the twentieth century, Regina was a household vacuum brand, and the company kept making them until the late 1990s. Somewhere in that is the whole arc of the music box: a machine built to fill a quiet house with sound, from a company that ended up making the loudest appliance in the home.

Where the music boxes are now

Plenty survive, and some of the finest can still be heard. The Morris Museum in Morristown, New Jersey, holds the Murtogh D. Guinness Collection, around 700 mechanical musical instruments and automata gathered over fifty years by an heir to the Guinness brewing fortune. He kept them in two side-by-side townhouses on Manhattan's Upper East Side, living among his machines and hosting playing parties for fellow enthusiasts. Today the museum plays them for visitors.

Museum Speelklok in Utrecht and the music box museum in Sainte-Croix do the same in Europe, and the Musical Box Society International, which Guinness helped lead in its early years, connects the collectors and restorers who still re-pin cylinders, re-tune combs, and coax old springs back into service. It's slow, exacting work, and the people who do it tend to talk about the machines the way other people talk about old friends.

Why they stay with me

Music boxes are exactly the sort of object I find irresistible: ingenious, beautiful, slightly mysterious, and capable of carrying a story long after the people who owned them are gone. A pinned cylinder is a kind of letter. Someone chose every note, set every pin by hand, and sealed it inside a box that might outlive them by a hundred years.

That fascination is where my novel The Unfinished Pirouette began. It centers on a 1920s wind-up ballerina whose tune breaks off partway through and slips into a second, hidden melody that nobody should have been able to hear. Some of what my restorer, Greer Tolliver, finds inside that doll is real music box engineering, and the tall Regina disc machine in the book is based on the ones that came out of Rahway. The Vantreight Music Box Works and the town of Pellbrook, though, exist only in the novel. I just wish they didn't.

If you'd like to hear what happens when Greer winds her up, read The Unfinished Pirouette on Amazon.
