Accordion

Lore & Background

The accordion's basic form is believed to have been invented in Berlin in 1822 by Christian Friedrich Ludwig Buschmann, though one instrument discovered in 2006 appears to have been built earlier. An instrument called accordion was first patented in 1829 by Cyrill Demian in Vienna. Demian's instrument bore little resemblance to modern instruments, having only a left-hand buttonboard with the right hand operating the bellows. A key feature was sounding an entire chord by depressing one key, and it could sound two chords with the same key, one for each bellow direction (bisonoric action). The patent covered an accompanying instrument played with the left hand, small and light for travelers, and described instruments with both bass and treble sections, though Demian preferred the bass-only version for cost and weight reasons.

Reader's Guide

The accordion was introduced from Germany into Britain around 1828, noted in The Times in 1831 as new to British audiences, and soon became popular. It had become popular with New Yorkers by the mid-1840s. In Russia, the earliest known simple accordions were made in Tula by Ivan Sizov and Timofey Vorontsov around 1830 after receiving an early accordion from Germany. By the late 1840s the instrument was very widespread, with factories producing 10,000 instruments a year; by 1874 yearly production exceeded 700,000. After Demian's invention, other accordions appeared, some with only right-handed keyboards. English inventor Charles Wheatstone's 1844 patent for a concertina brought both chords and keyboard together in one squeezebox. Further innovations continue to the present, including various buttonboard and keyboard systems, voicings, mechanisms to switch voices, and modern electronics such as condenser microphones, tone controls, and MIDI sensors. The accordion is used in genres such as chamamé, forró, vallenato, merengue, norteño, cajun, zydeco, jazz, klezmer, and classical music, with many European conservatories having classical accordion departments.

Did You Know?

• The oldest name for this group of instruments is harmonika, from the Ancient Greek harmonikós meaning 'harmonic, musical'.
• Cyrill Demian's 1829 patent covered an instrument that could sound an entire chord by depressing one key.
• By 1874, over 700,000 accordions were produced yearly in Tula and neighboring villages in Russia.
• The concertina and bandoneon are in the same free-reed family but do not have the melody–accompaniment duality.

The Engine of Sound

The accordion produces its voice through a mechanism that has no moving parts in the traditional sense. A player compresses or expands a set of bellows, and this motion forces air through a series of pallets—small flaps that open and close in response to a pressed key or button. Once the air is released, it rushes past thin strips of brass or steel known as reeds, which vibrate inside the instrument's body to generate tone. To keep the sound clean and prevent air from leaking between reed blocks, valves are fitted on opposing reeds for each note, allowing the player to make the reeds sound louder without losing pressure. What sets the accordion apart from its free-reed cousins—the concertina, the bandoneon, and the harmonica—is its built-in duality: a melody section, called the diskant, sits on the right-hand side, while the left-hand side carries pre-set chord buttons and bass notes that supply accompaniment. The harmoneon attempts a similar split but softens the contrast. Meanwhile, the harmonium and American reed organ share the same aerophone family but are large enough to rest on a floor or table rather than be carried on the body.

From a Berlin Workshop to a Patented Idea

The basic form of the accordion is generally credited to Christian Friedrich Ludwig Buschmann, who is believed to have built the first example in Berlin around 1822, though a single earlier instrument surfaced in 2006. The name itself carries a long lineage: the oldest term for the instrument family is harmonika, drawn from the Ancient Greek word meaning harmonic or musical. The more familiar word accordion descends from the nineteenth-century German Akkordeon, rooted in Akkord, which simply means a musical chord or concord of sounds. In 1829, Cyrill Demian filed a patent in Vienna for an instrument that looked nothing like the modern squeezebox. His design featured only a left-hand buttonboard; the right hand was reserved solely for working the bellows. The key innovation Demian protected was the ability to sound a full chord with a single button press, and his instrument could even produce two different chords depending on whether the bellows were pushed or drawn—a bisonoric action. He preferred the bass-only layout for its lightness and lower cost, though his patent also described versions with both bass and treble sections. English inventor Charles Wheatstone later merged a melody keyboard with the chord mechanism into one instrument he called a concertina, in 1844.

A Sound That Crossed Oceans

The accordion's global footprint is inseparable from the great waves of European migration that carried people and their instruments to the Americas and beyond. In South America and the Caribbean, the instrument became woven into the fabric of popular music: it drives the Chamamé of Argentina, the gaucho, forró, and sertanejo traditions of Brazil, the vallenato of Colombia, the merengue of the Dominican Republic, and the norteño of Mexico. In Europe, North America, and other parts of South America, its role tilts more toward dance-pop and folk contexts. Yet the accordion has never been confined to any single genre. In the United States it is a staple of Cajun and zydeco music, and it appears regularly in jazz ensembles and klezmer performances. On the classical side, the instrument is featured in both solo recitals and orchestral works, and many European conservatories now maintain dedicated classical accordion departments. The instrument's portability and its capacity to produce melody and harmony simultaneously made it an ideal companion for traveling musicians, and that same versatility is what allowed it to slot into so many distinct musical cultures without losing its identity.

The Russian Factory Boom

The accordion's story in Russia is one of rapid industrial adoption. The earliest known simple accordions in the country were reportedly made in Tula around 1830 by two craftsmen, Ivan Sizov and Timofey Vorontsov, after they received an early German-made example. By the late 1840s the instrument had already become very widespread across the region, and the combined output of Sizov's and Vorontsov's workshops reached roughly ten thousand instruments per year. The growth curve was astonishing: by 1866, Tula and its neighboring villages were producing over fifty thousand accordions annually, and by 1874 that figure had surged past seven hundred thousand. The instrument's manufacture also spread well beyond Tula. By the 1860s, significant production was underway in the governorates of Novgorod, Vyatka, and Saratov. By the 1880s, the list of manufacturing centers had expanded to include Oryol, Ryazan, Moscow, Tver, Vologda, Kostroma, Nizhny Novgorod, and Simbirsk, and many of these locales developed their own local varieties of the instrument. The accordion thus became not just a musical object in Russia but a major industrial product, with production scaling from a handful of workshop-made units to hundreds of thousands per year within a single generation.
