Rhythmic Music and Dance may be traced back to as much as 10000 years to sprawling village cultures in a Garden of Eden like environment that existed across most of what is now the Sahara Desert. (Africa’s Great Civilizations Origins PBS Hour One.)
At that time the cyclic tilting of the earth returned and glacial retreats caused massive monsoons to move to the area creating massive lakes and rivers and explosion of plants and massive animal herds available for livestock communities.

For nearly 5000 years communities probably developed village music and dance integrated with daily life. Finally the energy of the monsoons moved the storms back south and the Sahara desert returned forcing the village cultures with all their music and dance to migrate in and out of the Sahara with the rains to finally create the great urban civilizations around the desert and then around the world.
