musical instrument consisting of a rectangular bellows expanded and contracted between the hands. Buttons or keys operated by the player open valves, allowing air to enter or to escape. The air sets in motion free reeds, frequently made of metal. The length, density, shape, and elasticity of the reeds determine the pitch. The first accordions were made in 1822 by Friedrich Buschmann in Berlin. Bouton added a keyboard 30 years later in Paris, thus producing a piano accordion. The accordion is frequently used in folk music. See concertinaconcertina

a musical instrument with free-beating metal reeds which are vibrated by wind pumped by bellows.

The German master K. F. L. Buschmann invented the first manual accordion in 1822. In the 1830’s and 1840’s the production of accordions arose in Russia, in Tula. Russian masters developed varieties of two basic types of accordion. In the first type, every button emits a different sound depending on whether the bellows are compressed or expanded. Examples of the first type are the Tula, the Saratov, the cherepashka, the Bologoe, the Beloborodov, the Kasimov, the St. Petersburg (a forerunner of the baian), and the mariiskaia marla-karmon’. They have the usual sound distribution in the diatonic scale: C1, E1, G1, C2, E2, G2, C3 when the bellows are expanded, and D1, F1, A1, B1, D2, F2, A2 when they are compressed. In the second type of accordion the expanding and compressing of the bellows does not change the pitch of sounds. Some accordions of this type are the viatskaia, the livenka, the rusianka, the eletskaia roial’naia (a forerunner of the accordeon), the Siberia, and the khromka (chromatic accordion), as well as national accordions, such as the Tatar, the kubos, the pshine, the komuz and the selective Azerbaijan. Besides the accordions listed above, accordions with one or two rows of keys as well as Viennese and German ones have always been available in Russia. Accordions are known as the most common musical folk instrument.
