The kim-kim or Udu is a plosive aerophone (in this case implosive) and an idiophone of the Igbo of Nigeria. In the Igbo language, ùdù means 'vessel' or 'pot'.[1] This is a hand percussion instrument and it is one of the most important instruments in Igbo music.
About
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. Instead of throwing it away, the owner started to drum it.[3]
Construction
Usually, the Udu is made of clay. Sometimes, the ashes of relatives are used to make them too,[1] but it also can be made out of plastic or glass. Today it is widely used by percussionists in different music styles.
Playing and technique
The Udu is played in two primary ways: it is either placed on the lap or secured to a stand using duct tape.[3] The player produces a bass sound by quickly striking the larger hole.[4] Various pitches can be achieved by adjusting the hand position over the smaller upper hole. Additionally, the body of the instrument can be played using the fingers, creating a diverse range of sounds.
