The Mauri society is made of different castes, your family (clan), your sex, your work (musician, mason etc.) and your subethnicity (Black Moor, Berber Moor, Arab Moor determine your position in the society. In 1076 Arabs attacked and conquered the large area of the ancient Ghana Empire. Berbers retained a niche influence by producing the majority of the region's marabouts (those who preserve and teach traditions) while the sub-Saharan Black population was dominated by the other two ethnicities.
Ethnic tensions and the sensitive issue of slavery – past and, in some areas, present – are still powerful themes in the country's political debate. A significant number from all groups seek a more diverse, pluralistic society.

It is similar to a kora, the traditional harp of Malian griots, and has a curved wooden pole inserted into the gourd, where anywhere between twelve and fourteen strings are attached with leather thongs. It is plucked with both hands like a harp and can also be used as a rhythm instrument by striking the soundboard. In combination with the tidnit, it creates a free-flowing landscape of polyrhythmic sounds for singers to perform to. This sound provides a vast palate for the passionate vocals performed by Mauritania’s singers.
The Algaïta is an oboe in use among Islamized populations in Africa. The double reed is connected to the short pipe with a conical enbout timber provided with a metal disk that serves to support the lips of the player. It's usually played in the presence of local dignitaries.

africamuseum.be said:The atumpan is the main talking drum of the Akan people. It is the most favoured instrument to play the bass part to accompany dancing. The atumpan is an open goblet drum on a base. It is played in pairs, usually by a master drummer using two angular sticks. The membrane is stretched across the head of the drum inside a metal ring, which is anchored to 7 to 8 conical pegs around the outside of the drum. The atumpan drum measures approximately 1 m in height and has a diameter of 45 cm at the top. Because of its weight, it is placed in a wooden stand at an angle during play. Alternatively, two long wooden sticks are inserted in two holes where the conical pegs usually go.
