Answer the following question: Information:  - The goblet drum (also chalice drum, tarabuka, tarabaki, darbuka, debuka, doumbek, dumbec, dumbeg, dumbelek, tablah, toumperleki or zerbaghali, / ALA-LC: "darbkah") is a single head membranophone with a goblet shaped body used mostly in the Middle East, North Africa, South Asia, and Eastern Europe. The African djembe-wassolou is also a goblet membranophone. This article focuses on the "Eastern" and "North-African" goblet drum.  - The Bambara are a Mandé people living in west Africa, primarily in Mali but also in Guinea, Burkina Faso and Senegal. They are considered to be amongst the largest Mandé ethnic groups, and are the dominant Mandé group in Mali, with 80% of the population speaking the Bambara language, regardless of ethnicity.  - A djembe or jembe (; from Malinke "jembe" ) is a rope-tuned skin-covered goblet drum played with bare hands, originally from West Africa. According to the Bambara people in Mali, the name of the djembe comes from the saying "Anke djé, anke bé" which translates to "everyone gather together in peace" and defines the drum's purpose. In the Bambara language, "djé" is the verb for "gather" and "bé" translates as "peace."  - West Africa, also called Western Africa and the West of Africa, is the westernmost subregion of Africa. West Africa has been defined as including 18 countries: Benin, Burkina Faso, the island nation of Cape Verde, Gambia, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Liberia, Mali, Mauritania, Niger, Nigeria, the island of Saint Helena, Senegal, Sierra Leone, São Tomé and Príncipe and Togo.  - The Bambara (Bamana) language, Bamanankan, is a lingua franca and national language of Mali spoken by perhaps 15 million people, 5 million Bambara people and about 10 million second-language users. It is estimated that about 80 percent of the population of Mali speak Bambara as a first or second language. It has a subjectobjectverb clause structure and two lexical tones.  - Dunun ( Malinké : ( du.nun ) ; plural dunun ) ( also spelled dundun or doundoun ) is the generic name for a family of West African drums that developed alongside the djembe in the Mande drum ensemble . A dunun is a rope - tuned cylindrical drum with a rawhide skin at both ends , most commonly cow or goat . The drum is played with a stick . Depending on the region , a plain straight stick , curved stick with flat head ( similar to the stick used for a tama ) , or a straight stick with a cylindrical head attached at right angles near one end may be used to strike the skin . Traditionally , the drum is played horizontally ( placed on a stand or worn with a shoulder strap ) . For a right - handed player , the right hand plays the skin and the left hand optionally plays a bell that may be mounted on top of the drum or held in the left hand . The latter style is popular in Mali and originally from the Khassonké people . Three different sizes of dunun are commonly played in West Africa . The dundunba ( also spelled dununba ) is the largest dunun and has the lowest pitch . Typical size is 60 -- 70 cm ( 24 -- 28 in ) in length and 40 -- 50 cm ( 16 -- 20 in ) in diameter . `` Ba '' means `` big '' in the Malinké language , so `` dundunba '' literally means `` big dunun '' . The sangban is of medium size , with higher pitch than the dundunba . Typical size is 50 -- 60 cm ( 20 -- 24 in ) in length and 30 -- 40 cm ( 12 -- 16 in ) in diameter . The kenkeni is the smallest dunun and has the highest pitch . Typical size is 45 -- 50 cm ( 18 -- 20 in ) in length and 25 -- 35 cm ( 10 -- 14 in ) in diameter . Dunun are always played in an ensemble with one or more djembes .  - Mali, officially the Republic of Mali, is a landlocked country in Africa. Mali is the eighth-largest country in Africa, with an area of just over . The population of Mali is 14.5 million. Its capital is Bamako. Mali consists of eight regions and its borders on the north reach deep into the middle of the Sahara Desert, while the country's southern part, where the majority of inhabitants live, features the Niger and Senegal rivers.
