recorder

n. registrar, one who makes and maintains records; machine that can record; type of musical instrument that resembles a wooden flute and produces a high-pitched sound

The recorder is a  woodwind musical instrument of the family known as fipple flutes or internal duct flutes — whistle-like instruments which include the  tin whistle and ocarina. The recorder is end-blown and the mouth of the instrument is constricted by a wooden plug, known as a block or fipple. It is distinguished from other members of the family by having holes for seven fingers (the lower one or two often doubled to facilitate the production of semitones) and one for the thumb of the uppermost hand. The bore of the recorder is occasionally cylindrical but is usually tapered slightly, being widest at the mouthpiece end.
