This 7-stringed instrument originates in Central Africa and is not a traditional Baka instrument. It has been adopted by the Baka over the last 30 years or so and is commonly played by both men and women.
The strings are made from nylon fishing line. These are attached to a wooden neck and a sheet of tin (flattened piece of tin can) which covers a wooden sound box. It is held with the neck away from the player, the strings being plucked from both sides.
