1911 Encyclopædia Britannica/Ocarina
OCARINA, a wind instrument invented in Italy, which must be classed with musical toys or freaks, although concerted music has been written for it. The ocarina consists of an earthenware vessel in the shape of an egg with a pointed base and a tube like a spout in the side, which contains the mouthpiece. There are usually 10 holes in the front surface of the instrument, nine for fingers and thumb and a vent hole; the newer models have 8 holes and two keys. By half covering the holes the semitones are obtained.
