This is a dangerous sound to do - so do not try it unless you are an experienced beatboxer. I'm not lying when I say I was bleeding from my mouth because of it - it's the only beatbox sound that's had any kind of negative effect on me! Take care, take plenty of breaks, keep yourself hydrated, and be sensible. If it even vaguely hurts, stop!
It took a lot of practice and experimenting with different "methods" of pressure before I got this sound. A UK beatboxer called Marv-Ill has them absolutely mastered, as does Roxorloops.
Standard Beatbox Notation (SBN)
{ * }
- Open your mouth slightly
- Put your tongue against the roof of your mouth. It should pretty much cover most of your teeth too
- Suck hard, as if sucking your tongue. You should still be able to breathe through your nose - this is evident by the fact you can hum making this sound
- Open your jaw wider at the same time as snapping your entire tongue off of the roof of your mouth
You might get a slight "duck calling" sound. This is perfectly normal and is a sign you're on the right track. Things to check if you can't get the sound are the positioning of your tongue and the amount of pressure.
