One In another exemplary embodiment, an ocarina has a body type of flute is a whistle flute or fipple flute, which employs having a plurality of apertures disposed therein. The body is a whistle-type mouthpiece and is among the most ancient of 25 formed by an inner liner defined by at least one sound all musical instruments.

Most types of wind instruments employ an open-ended In any embodiment, the inner liners are manufactured tubular- or conical-shaped cavity to produce sound, whereas 35 ocarinas utilize an enclosed sound chamber or cavity.

The advantages of this inner liner/outer shell sound chamber, and a plurality of toneholes that penetrate design are several. First, the inner liners, which are prefer- ably formed of an easily-manufactured, water resistant, into the enclosed chamber and that are used to control the 40 pitch sounded by the instrument. relatively poor heat conducting material, serve to protect wood- or metal-shelled ocarinas (or ocarinas fabricated of Ocarinas may be fabricated from a variety of materials, similar materials) from the adverse effects of moisture. such as ceramics, wood, metal, plastics, and the like.
