This video teaches the bare basic sounds for beatboxing and gives you some simple beats to start practicing with.
To help you out with timing, use the online metronome at http://www.metronomeonline.com/.
Here's how you make the sounds:
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.
This was the very first video I made in my beatboxing tutorial series, so if you want to see a newer and updated version, check it out here on YouTube.
