Ngoni is the Bambara name for an ancient traditional lute found throughout West Africa. Though typically a small instrument the ngoni has a big sound and a big place in the history of West African music. Its body is a hollowed-out, canoe-shaped piece of wood with dried animal skin stretched over it like a drum. The neck is a fretless length of doweling that inserts into the body, which unlike the kora (whose neck goes totally through its calabash resonator) stops short of coming out the base of the instrument. For this reason musicologists classify the ngoni as a "internal spike lute." The ngoni's strings (which are made of thin fishing line like the kora) are lashed to the neck with movable strips of leather, and then fed over a fan-shaped bridge at the far end of the body. The string closest to the player actually produces the highest pitch, and the player plucks it with his thumb, just like a 5-string banjo. This feature, coupled with the fact that the ngoni's body is a drum rather than a box, provides strong evidence that the ngoni is the African ancestor of the banjo.

Instruments of this general construction can be found from Morocco to Nigeria, and everywhere in between. Some are very large, such as the gimbri played the mystic Gnawa brotherhood of Morocco. Others are tiny, such as the one-stringed gurkel of northern Mali. In Senegal the Wolof call it xalam (pronounced: halam) while in the Gambia the Mandinka have a 5-string version they call kontingo. The version played by the Manding griots of The Gambia, Mali and Guinea is typically about two-feet long and has either four or seven strings.

In recent years, some great young instrumentalists have developed the ngonis technical range. Perhaps the foremost ngoni modernizer in Mali is Basekou Kouyate of Segou. Basekou's father played the large ngoni, like Banzumana. But like most of the current generation, Basekou gravitated towards the small, high-pitched version of the instrument. Basekou now leads his own band Ngoni Ba and has played in an instrumental Manding music power trio with Toumani Diabate (kora) and Keletigui Diabate (balaphone). All of these players are modernizers who bring in Western and other influences into their music. Since the ngoni remains the most popular traditional string instrument in Mali, there are many other great young players who have made places for themselves within the griot tradition. Among the most sought-after ngoni players these days are Sayan Sissoko, Mama Sissoko and Moriba Koita.
