<P> Conch shells have also been used as primitive instruments since Neolithic times, and must be numbered among the antecedents of the natural trumpet . The four shells most commonly used for this purpose are the triton or trumpet shell, the cassis or helmet shell, the fusus, and the strombus or true conch, though the term "conch - shell trumpet" is generally applied to all instruments of this type . The spiral interior of the shell acts as tubing, and a mouthhole is created either by breaking off the point of the shell (end - blown conch) or by boring a small hole in the body (side - blown conch). The cassis is an end - blown shell; the other three types are usually side - blown . </P> <P> Conch - shell trumpets are found in almost every part of the globe, including inland areas like Tibet, Central Europe and the Andes .

In the South Pacific island nation of Vanuatu, local fishermen use conch - shell trumpets known as tapáe to call for assistance when they are drawing in their nets . In Fiji, the davui conch - shell trumpet is still blown to invoke the gods . </P> <P> End - blown conch - shell trumpets are still used as sacred ritual instruments in Asia . The Indian śańkh or śańkham is blown by Brahmins in Hindu temples throughout India and South Asia, and is also used today as an instrument of folk music and dance; formerly it was employed as a heraldic instrument to declare war or celebrate victory . According to Hindu mythology the śankh will be blown by Siva at the end of the current World Age as a sort of Last Trump . </P> <P> The conch shell is also used as a signal in Buddhist ceremonies in the Far East . In Tibet it is known as the dun - dkar, or dung - dkar; in China it is the faluo or hai lo, and in Japan the horagai or hora . </P>
