The rectangular resonating body of the musical instrument is made of wood (hollowed out). A round resonance hole is located on the upper side above the bridge (made of wood) with 16 thin lamellae made from the ribs of the leaves of the raffia palm. The lamellae are held (wrapped) by two thin raffia leaf ribs. The resonator is wrapped with plant fibres in three places - at the top, in the middle and at the bottom. The hole on the underside is sealed with resin. The entire surface of the sound box shows signs of use, especially on the right and left above the bridge.
