The kim-kim or Udu is a plosive aerophone (in this case implosive) and an idiophone of the Igbo of Nigeria.
Actually, being a water jug with an additional hole, it was played by Igbo women for ceremonial uses.
[2] Legend says that the Udu drum was made accidentally because a punched hole was on the side, making it useless.
The Udu is played in two primary ways: it is either placed on the lap or secured to a stand using duct tape.
Additionally, the body of the instrument can be played using the fingers, creating a diverse range of sounds.
