Accordion, portable reed organ used for jazz and folk music. Tuned metal reeds are set in vibration by air directed at them from a central bellows through valves operated by piano-type keys on the instrument's right-hand side. Buttons on the left produce chords. Although they were known in ancient China, the first modern accordions were built in 1829 in Vienna.
