hi hawaouti, thanks for bringing up these questions. i'll attempt to answer some of them.
HawaOuti wrote:In the list of traditional rhythms there are some that are not originally played with djembe:
Lengjen - if it refers to mandinka rhytm in Gambia and Casamance, then it is played with seuruba drums
Warba - mossi rhythm from Burkina? No djembes at least 20 years ago.
Bao - is it played with djembes?
Djole - originally with siko drums
Kebendo - is it a djembe rhythm? I know it is a balafone rhythm but often played with yole
Liberte - djembe, yes, but not traditional (from 1968 or something like that..?)
Just some questions, correct me if I'm wrong! Also it would be nice to know about the baga rhythms, they can't be all originally djembe rhythm, or can they?
yes, not all rhythms currently played were traditionally played on djembe ensemble. the susu live close to the baga, landuma, nalu, and down south to the mandinye and temne. it's not surprising to find an exchange happening and seeing the djembe being adopted by these ethnic groups, particularly after its popularisation as an instrument with the ballet. also, the ballets sought out rhythms from the various ethnic groups of guinea, so a transcription of non-djembe music to djembe happened which has become classic in conakry, and made its way into the urban tradition.
djole and gumbe is nowadays often played on djembe in sierra leone, where these rhythms originated (see videos in the jole thread), as well as the drums they were originally played on. there is also caribbean influence in these 2 genres, and of course caribbean drum music is another manifestation of traditional african music blended together with so called 'new world' influences... a case of african music coming 'full circle' through the diaspora and back.
speaking of diaspora, there is a big djembe scene in the caribbean, as well as reunion island. they are playing their own rhythms on the djembe. the rhythms from reunion are quite interesting!
lengjen - mandinka people, a branch of the people of mali from whom the djembe originated. closely related to malinke people, yet the mandinka culture is centred in cassamance, a very small area where several ethnic groups live in close proximity, which gave birth to their unique type of music.
warba - since the mossi are the dominant ethnic group of burkina faso, this would almost be the national rhythm. not surprising to find it played on the most popular drum in burkina. similarly, all kinds of ghanaian rhythms being played on djembe, as well as senegalese rhythms (wollof and other ethnic groups).
I think the fast and furious Guinea or Burkina style is quite recent, even in the 20 years time I have been travelling there the style has changed a lot.
a very valid point, it's constantly changing.
i hope this helps. to me, it opens up many more questions
