Certainly the origin of the blues as we know it today. It also plays well as binary or ternary measures 2, 3 or 4 beats.
The blues is based on pentatonic scale.
The particularity of this music is that it is tonal, e.g. there is usually no chord or a single chord, neither major nor minor, consisting of tonic octaves and fifths notes.

a hollowed out tree trunk on which a dried animal skin tends and, according to its diameter, a much greater power than the human voice. It is assumed that the melodies of every first songs were inspired by the different heights of djembes, then other instruments such as the kora and balafon, were created.
