Complete Encyclopaedia of Music/A/Aeolodicon
Aeolodicon. A keyed instrument whose tones are produced by thin pieces of metal so placed as to play, freely, being put into motion by means of a current of air. By the pressing down of a key, a kind of wind chest is opened, and while the air, compressed therein by a species of bellows, flows out against the metallic spring or plate, the latter is put into a vibrating motion, and produces a tone which is still further modified by the manner of pressing down the key.
