Clicks. There's really not much I can say here. So... um, the weather's sure nice today, isn't it?

To make the sound

1 - Have your tongue on the roof of your mouth
2 - Build up a little pressure
3 - Release. That's all there is to it!
4 - There are a great deal of variations to this simple sound, but these are covered in other tutorials. Check out the tongue clop and block click tutorials for a couple of ideas!

Peace, love, and sweet simplicity
