The New Student's Reference Work/Accordion

Accordion (ăk-kor′dĭ-ŭn), a musical instrument invented by Damian, at Vienna, about 1829. It is made on the principle of a bellows, the sound being produced by the action of wind on metallic reeds. Keys are ranged on each side, which are touched by the fingers as the instrument moves backward and forward. It is manufactured chiefly in Paris.
