Thanks to those of you who referred me to Mohammed Diaby's "Karamba Dinke" or an example of Touba.... Below is what I hear on Diaby's CD. (The middle djembe part is VERY hard to hear - the OoOs is clear, but what happens on the other side is questionable. @ muffed tones.) The handing indicators are obviously just my guess.
One thing I found interesting - The liner notes indicate that the rhythm is "traditionally played on tall Gumbe drums", which have thin cowskin heads. The djembe pattern on the CD sounds the same as is played in many of the Gwoka arrangements form Guadeloupe.
