Traditionally it was a water jug with another hole in the side, played by women for ceremonial music. Udus have a side hole which creates a deep reverberating note when struck with the flat palm of the hand. The clay body of the vessel produces a high pinging sound when struck with the fingers. The combination of these two techniques sometimes sounds similar to the Indian tabla or African talking drum.</p>"

CONTENT[13] = "<h3>Ehru</h3><div align=\"center\"><img src=\"images/ehru.jpg\" alt=\"Ehru\" width=\"156\" height=\"114\" border=\"0\"></div><p>The Erhu is a bowed two-stringed instrument. It has a long round neck of hardwood attached to a hardwood resonator, usually covered with snakeskin. Its steel strings are tensioned between the tuning pegs at the neck's upper end, and the lower edge of the resonating box. The speaking length of the string extends from a nut at the peg end of the neck to a bridge placed upon the resonator. The horsehair bow, rosined on both sides, is inserted between the strings, and the strings are played one at a time, virtually never together. The player fingers the strings not by pressing them against the neck but by placing them on the strings lightly, to create different speaking lengths.</p>"
