The whistle scratch is a simple scratch that sounds similar to a dog whistle. Some beatboxers have really mastered this technique that enables you to scratch and beatbox at the same time.
How it's done
- To make this sound your top lip should overhang your bottom lip. Pretend having 'granny lips' - imagine you have no teeth!
- With your tongue placed in the gap between your lips (without touching) you should be able to breathe out channeling air under your tongue to make a whistly airy noise.
- You can change the shape of the whistle by moving your lower lip to expose your front lower teeth and gums
