This video provides four exercises for playing African rhythms where the counting is in 'threes'.
There is an easy exercise which for many people comes naturally; one which is a little trickier to feel; a harder exercise and finally a nice challenge exercise at the end.
All these patterns lend themselves to 12/8 and 6/8 patterns for West African djembe and Dundun drumming. Good luck with it and do leave us a comment on the video to tell me how you get on.
