(earlier recordys, mid-14c.), from record (v.) in an archaic sense of "quietly sing or repeat a tune, practice a tune," used mostly of birds.

The musical instrument was known to Shakespeare and Milton ("In perfect phalanx to the Dorian mood/Of flutes and soft recorders," "Paradise Lost"), but the name, and the device, were rarely heard by mid-1800s (it is marked "obsolete" in Century Dictionary, 1895), ousted by the flute, but both enjoyed revival after 1911 as an easy-to-play instrument for musical beginners.
