Answer:
Well I think that African slit drums traveled globally in prehistory..because they have them in melanesia, smller one's in polynesia and they did have them in central America...so it's a question of which way did they travel..they predominantly have them in west Africa but I've heard that the sudanese have them too....interesting, I got taught how to play some melanesian and polynesian rythms, but am of African ancestry, so I'm always asking myself the same question!!
