This is the so-called "Makonde/Mwera type" of lamellophone, with the hook-shaped, solid and relatively wide (7.5-9 mm) iron reeds. These are hooked directly and immovably into the resonance box at its upper edge, forming an angle of about 60 degrees. They are so firmly fixed in the wood that the tuning cannot be changed. A bridge is therefore unnecessary for this type of lamellophone. The instrument shows signs of damage from transport, especially from pressing. There are five round resonance holes arranged in a row in the centre of the soundboard. A side view of the "Makonde/Mwera" lamellophones reveals the bed-shaped curved form of the sound box and the fact that, in contrast to many box-shaped lamellophones from other regions of Africa, the sound box here is hollowed out from the back and was also closed from the back by nailing on a wooden soundboard.
