Accordion 19th century model bellows instrument Magnet

Accordions (from 19th-century German Akkordeon, from Akkord—"musical chord, concord of sounds")[1] are a family of box-shaped musical instruments of the bellows-driven free-reed aerophone type (producing sound as air flows past a reed in a frame), colloquially referred to as a squeezebox. A person who plays the accordion is an accordionist. The concertina , harmoneon and bandoneón are related. The harmonium and American reed organ are in the same family, but are typically larger than an accordion and sit on a surface or the floor. The accordion is played by compressing or expanding the bellows while pressing buttons or keys, causing pallets to open, which allow air to flow across strips of brass or steel, called reeds.
