Accordion facts and history

Patented in Vienna in 1829, spread by factory production, adopted worldwide, then mocked and rehabilitated. The accordion's strange two-century career.

The 1820s: several people, roughly at once

The free reed reached Europe from Asia, where mouth organs of the sheng family had used vibrating tongues for centuries. By the 1810s and 1820s European instrument makers were experimenting with the principle in every direction at once, and a cluster of inventions arrived within a few years of each other.

The name and the patent belong to Cyrill Demian, an Armenian-born maker working in Vienna, who registered his Accordion in May 1829 with his sons. The distinguishing idea in the patent was that a single button sounded a whole chord, an accord, which is where the name comes from. Around the same period Charles Wheatstone in London was developing the concertina, and Friedrich Buschmann in Berlin had already been working on free-reed instruments including the handaeoline.

Demian's instrument was small, diatonic and bisonoric, meaning each button gave one note pushing and a different note pulling. It had no separate melody keyboard as we would recognise it. Almost everything that makes a modern accordion took another seventy years of incremental work by dozens of makers.

How it got everywhere

The accordion spread with extraordinary speed for a nineteenth-century object, for an unglamorous reason: it was manufacturable. Castelfidardo in Italy and Klingenthal and Trossingen in Germany turned into accordion towns, and factories there produced instruments in volume at prices working people could reach. One box gave you melody, bass and chords, so a single player could supply a whole dance.

That made it the portable, weatherproof, self-sufficient instrument of emigration. It travelled with people to Argentina, Brazil, Mexico, the United States, South Africa, Madagascar and across the Pacific, and in nearly every place it landed it was absorbed into a local music rather than replacing one. Cajun and zydeco, Colombian vallenato, Brazilian forró, Mexican norteño, Irish and Scottish dance music, klezmer, Basque trikitixa, Chinese and Korean folk ensembles: all of it dates from that diffusion.

The related bandoneon, developed in Germany as a portable instrument for chapel use, went to Buenos Aires with German and Italian emigrants and became the defining sound of tango, which is one of the odder career changes in instrument history.

The peak, then the fall

By the 1930s and 1940s the accordion was a mainstream instrument in Europe and North America. It was on the radio, in dance halls, on variety shows and in the hands of hundreds of thousands of children taking lessons at neighbourhood studios. In the post-war United States it was one of the most commonly studied instruments in the country, taught through chains of franchised schools.

Then it collapsed, fast. The usual explanation is the electric guitar and rock and roll, and there is something to that, but the accordion also suffered from being the sound of your parents' entertainment at exactly the moment when youth culture became a market. By the late 1960s it had gone from modern to hopelessly square, and the teaching networks that had sustained it emptied out.

What followed was thirty years of the instrument as a punchline, an unfair reputation built mostly on hearing it played badly at weddings.

The long rehabilitation

The recovery came from several directions and none of them was nostalgia. Astor Piazzolla, on bandoneon, forced the tango world and then the concert world to take his instrument seriously. In the Soviet Union the bayan entered conservatories and acquired a real concert repertoire, with Vladislav Zolotaryov and then Sofia Gubaidulina writing for it. Northern Europe produced composers and players who treated the accordion as a normal modern instrument, and Arne Nordheim wrote for it in Norway.

Meanwhile folk revivals kept the popular traditions alive, and from the 1980s onward the accordion turned up in indie rock, film scores, Balkan brass, and anywhere a director needed something that sounds like memory. Today the instrument occupies an unusual position: entirely normal in half a dozen serious musical worlds, and still a mild surprise to people who have not met one for a while.

A few facts worth keeping

The accordion has no strings and no air column, only steel reeds. It cannot be tuned by adjusting tension; a tuner files metal off a reed, which is why the job takes hours and is not reversible if done badly. The Stradella bass layout, the row of preset chords under the left hand, was standardised in the nineteenth century and has barely changed since.

Castelfidardo still makes accordions and still has a museum devoted to them. And the instrument remains a genuinely global object: it is easier to list places with no accordion tradition than places with one. That range is part of why we keep a free score library of more than 740 pieces at A&G Academy in Singapore, covering everything from Bach transcriptions to tango and folk.

Frequently asked

Who invented the accordion and when?

Cyrill Demian patented an instrument called the accordion in Vienna in May 1829. He was not working alone in a vacuum: Friedrich Buschmann in Berlin and Charles Wheatstone in London were developing related free-reed instruments in the same decade. Demian's version gave each button a full chord, which is where the name came from.

Why did the accordion become unpopular?

It peaked in the 1940s and 1950s as a mainstream household instrument, then declined sharply in the 1960s. Rock and roll and the electric guitar took the young audience, and the accordion became associated with the previous generation's entertainment. The teaching networks that had supplied thousands of students collapsed within about a decade.

What countries have the strongest accordion traditions?

Italy, France, Germany, Russia and Finland in Europe; Argentina through the bandoneon and tango; Brazil, Colombia and Mexico in Latin America; Ireland and Scotland for dance music; and Louisiana for Cajun and zydeco. It also took root in South Africa, Madagascar and parts of East Asia after nineteenth-century trade and emigration.
