Your Guitar's Body Is Useless (And Has Been Since 1932)

Pull a string tight and pluck it. On its own it is almost nothing — a thread of wire pushing almost no air, making almost no sound. Everything else is an answer to that. The box beneath it. The bowl. The arched belly, the two carved holes. For five thousand years the history of the string instrument is the history of making a nearly silent object loud enough to hear. And then, in nineteen thirty-two, somebody solved it another way, and all of it became unnecessary.

Almost every telling starts the same way. A hunter draws a bow, hears the string sing, and music is born. It is a good story. There is no evidence for it at all. Not one string instrument survives from the Palaeolithic, anywhere. The proof everyone reproduces is a figure on a cave wall in the Pyrenees — and nearly every copy of it descends from a tracing made by a priest in the nineteen twenties, who stands accused of drawing what his theory needed. Curt Sachs, who founded the study of instruments, threw the idea out. The oldest musical bows we can document are ten feet long, and useless as weapons.

The oldest stringed instruments we can put in a case come out of the ground at Ur, around two and a half thousand years before Christ. What matters about them is not the gold. It is the box. Somebody had understood that a string alone will not carry, and that stretched across a hollow chamber, the chamber will move the air for it. The whole principle, already solved. And there is something the photographs do not tell you. The wood had rotted entirely, leaving a shaped hole in the soil, so Woolley poured plaster into the ground to record the shape before it was lost. What stands in the case today is a modern frame built from that record, carrying the original gold and shell and lapis. The oldest instrument in the world is a reconstruction wearing a Bronze Age face.

The box spread. Harps in Egypt, buried with their players. A zither from a tomb in Hubei, seven hundred years before Christ. In Greece, the lyre — and the story that Pythagoras passed a forge, heard hammers ringing in harmony, and discovered that music was arithmetic. He did not. That account was written six hundred years after his death, and the experiment does not work: hammer weight does not govern pitch. The instrument he supposedly used appears in no surviving text until two centuries after he died.

Here is the part almost nobody tells you. For the first three and a half thousand years, every string on earth was plucked. You touched it, and the note began dying the instant it was born. Then, around the year one thousand, somebody drew a bow across a string — and it simply kept going, for as long as the arm moved. A plucked string is an event. A bowed string is a voice. And it does not appear in one place and spread outward. It turns up in China, in North Africa, in the Near East, in the Balkans and in Europe, within a couple of centuries of each other. Whether that means one origin or several, nobody has settled.

The instruments moved along trade routes, and so did their names — which is why English has been calling one of them 'the wood' for seven hundred years without noticing. The Arabic is al-oud. The wood. It crosses into Provençal, the article fuses to the noun, and reaches English as lute. There is a better one. The Latin vitula splits: down the Germanic branch it becomes fiddle, down the Romance branch, viola. The same word, and nobody hears it.

In northern Italy, in the middle of the sixteenth century, the problem gets its most famous answer. Arched plates carved thin. A bar underneath. Two f-shaped holes to let the box breathe. Within a hundred and fifty years the violin reaches a shape that has not meaningfully changed since — and the usual explanation is that it cannot be improved. In twenty fourteen somebody measured it. Four centuries of instruments, thousands of outlines, set against the makers who made them. The fine details of that shape do not track sound. They track lineage. Violins look the way they look because makers copied their teachers, imperfectly. It is not optimisation. It is descent.

Which brings us to the most valuable objects in the story, and the most persistent claim about them: that a Stradivarius sounds better, and that we have lost the secret. Between twenty twelve and twenty seventeen this was tested three times, properly. Soloists in darkened rooms, welder's goggles on; the first of the three went as far as scent on the chinrests, to defeat even smell. Asked to choose, they preferred the new violins by six to one. Asked which was which, they were at chance. And almost every surviving Stradivarius was rebuilt in the nineteenth century for a louder age — the neck lengthened, a heavier bar, steel where there had been gut. The instrument people revere is a Baroque body carrying a Victorian rebuild.

That last change happened faster than anything else here. Steel strings had existed since the eighteen seventies and been dismissed as an abomination. Then the First World War stopped the gut trade, and the sheep intestine that had made violin strings for four hundred years was requisitioned for surgical sutures. Within three years, practically every concert violinist had changed over. Louder, brighter, under more tension.

By then the box was being asked for more than it could give. And in nineteen thirty-two a company in Los Angeles put an instrument on sale that answered the problem another way. A magnet, a coil of wire, the string moving through the field between them. The vibration becomes current directly. Nothing has to be made loud, because nothing has to move any air. And you can see they knew exactly what they had done, from what they made it out of. The body is cast aluminium. It is a terrible soundboard, and it does not matter, and that is the entire point.

Put them in a row. A lyre from a grave at Ur. A lute whose name means the wood. A violin from Cremona. A guitar from a Spanish workshop. And a slab of cast aluminium. The first four are machines for making a quiet thing loud. The fifth is not a machine for anything. It is somewhere to put the strings.

When George Beauchamp filed the patent, in nineteen thirty-four, the instrument had already been on sale for two years. The examiners sat on it for three more. They were not sure a body that made no sound could be a musical instrument at all. It took the Patent Office five years to accept that a thing which makes no sound could be an instrument. Most of us managed it in the length of a song.

Pull a string tight and pluck it. It is still almost nothing. The difference is that now, nothing has to make it loud. Five thousand years of boxes, and bowls, and bellies, were the answer to a question we stopped asking in nineteen thirty-two. The string never changed. We just stopped needing to hear it.
