For instance, in America, these kinds of drums are referred to as the doumbek. They are widely used in E. Europe, N. Africa and a larger part of Asia. Good examples of these kinds of drums include the Bendir, Riq, Tamburine, Irish bodhran etc. These drums are mostly made of wood which forms almost a perfect circle.
These high-quality drums are carved from Tweneboa wood, a resonant, somewhat plentiful preferred drum making wood in Ghana. The skins are stretched over the tops of the drum shells and fastened with strong pegs that fit snugly in the drum shell. The tall fontomfrom drum has a thunderous sound (the drum sound imitates it's name) that, played correctly, can be heard from a long distance. Timbre-wise, atumpans are more mid-range and complement the bassy fontomfroms well. Both of these types of drums are headed with a medium to heavy cow skin. The sound of the apentema again imitates it's name, tonal wise it may compare to some congas and is played with hands or sticks. The apetia is the baby drumâplayed with two sticks, it is tuned to make a bright repetitive sound.
