The bolon, also called M'Bolon, is a traditional harp played in Mali and Guinea. It was often used in hunting ceremonies or before battles to encourage bravery. The Jola people in Gambia used it to go along with group singing by men. In Guinea, the bolon is the oldest of its kind among string instruments.

The bolon has three strings. It is made from a large calabash covered with goat skin that has not been shaved, and it has a curved neck shaped like a bow. When playing, the musician places the instrument between their legs, with the strings facing them. The musician plucks the strings and also hits the calabash, like striking a drum.
