Good evening all.

I've been at this for weeks, completely no luck online. So I wanted to make a post on here, and ask for help.

I know that genetically, I can make the sound. Thing is, all tutorials on YouTube I've watched, as well as websites I've read, are all really vague. They basically boil down to:

1. Relax your tongue, jaw & mouth.

2. Point your tongue upwards.

3. Breathe out

4. Let your tongue vibrate

That's my problem, I want to know how to physically make my tongue vibrate. I'm a beatboxer, so imagine you ask me how to do throat bass. I just say, you do throat bass. That's what this is like for me. Doesn't mean anything. Anyone have any tips on learning this sound? I breathe out and my tongue doesn't flutter. My uvular does, but how do you make your tongue vibrate? Can it be learned or can people just do it right away?

Thanks in advance.
