Have you checked this thread, nodrog?
music-and-drumming/two-more-slap-tones-t607.htmlLike you, I have some background and experience with other kinds of non-Western percussion. I've talked about that in the thread I linked to, but that's only a small part of the overall take contributed by many who post here.
Enjoy, and don't worry too much about whether something is "correct" or not - meanwhile working on the basic slap and tone strokes used in trad. djembe playing. I'm sure you'll find more ways to transfer skills from one kind of drum to another.

I also have about 40 years experience of drumming on desk tops and I'm sure this helps in coaxing different sounds from the djembe.
Absolutely! I'm big on car steering wheels, myself - also walls and books and cardboard boxes and water bottles and metal saucepans and buckets and wooden cabinet doors and railings and just about anything else that I can use to create sound. (Cardboard boxes are one of my faves as far as "found" instruments, actually. They can sound great when played with both hands and brushes.
