Mongolian shaman's jew harp.
It made of brass and two horse is
soul of the jew harp.
1) The Jew's Harp consists of a cast copper or brass frame and a tempered
steel tongue. The tongue of the instrument lies between the jaws of
the frame and is played by vibrating the tongue, which is done by
striking or plucking, with the forefinger.
2) Take the Jew's Harp lightly in the hand, using care that the hand
touches only the frame and not the tongue.
3) Place the harp against the front teeth, which must be slightly apart.
4) The upper and lower lips should rest on the top and bottom of the
frame.
5) With your forefinger, pluck the tongue of the Jew's Harp, either by
pushing or pulling. While the harp's tongue is in motion, silently
pronounce the vowels (A-E-I-O-U). This is an easy way to learn
how to produce sounds, which occur by altering the size of the
mouth cavity.
Using small amounts of air (either inhaling or exhaling) will alter the
sound quality. Moving your tongue (thus changing the size of the mouth
cavity) and using small amounts of air will, in no time at all, produce
many different tones. You then combine this with the rhythmic beat of
the music. Now, you can play any song you wish!!
