khassonke musical instruments include:
dundungo - medium sized, slightly elongated dunun made from bumun wood, traditionally covered with deer skin. due to the relative scarcity of deer skin, semi-tanned goat skin is most often used nowadays. the dunun is worn slung over the shoulder and played with a curved stick while the other hand plays a bell (nanga).
jingo - small dunun played without a bell.
tantango - a peg drum made of duguto (dugura) wood and half-tanned bull skin, played with bare hands for weddings, baptisms or the death of a village elder. it is also used to signal danger, or to guide a person home who is lost in the bush. often 2 people play this drum - one with the hands and the other with sticks.
tamandingo (sing. tamo) - tension drums or 'talking' drums played exclusively by griots who place them under the arm in order to change the tension of the skin using pressure from the arm and beat the skin with a curved stick.
tabulo - this bowl-shaped drum made from duguto (dugura) wood and half-tanned bull skin was played with bare hands to announce the death of a king or chief. it can only be found in some villages nowadays.
kontingo - a 4-5 string lute made of hard wood such as dugura, covered with bull skin. the strings were traditionally made from braided horse hair, but fishing wire is easier to replace and is commonly used nowadays. it is played exclusively by griots, who pluck the strings with their fingers.
khirongo - a 1 string lute similar in shape to the kontingo.
simbingo - a 7 string harp lute covered with deer or goat skin played exclusively by musicians initiated into the hunters' society. same as the donsongoni.
