Tutorial

Step 1 Kick Drum

Make a "buh" sound.  It's like saying "boo" without the "oo".  Build up pressure behind your lips to make it louder.

Step 2 Hi-hat

Make a simple "t" sound for the closed hi-hat.  Add a hiss afterward for the open hi-hat.

Step 3 Rimshot

Make a "kuh" sound using the back of your tongue.  If you are having trouble, push the back of your tongue against the top of your mouth and force air from your throat over it.  You should get a kind of "strangling" sound.  Make this sound shorter and you'll have the rimshot perfectly.
