So, the purpose of this video

I want to make a "Double Ralik Whistle" Tutorial for all of you

So, you call it "Hii"

After that close your tongue

Go up to the ceiling and don't cover everything

leave empty in the middle

"TUTORIAL PRACTICE"

So, the second part

after you can "Ralik Whistle"

like this one

so, while you do "Ralik Whistle" that

You have to close the front lip

Cover tightly

As you can see, at the end of my lips I didn't close tightly

Because, I want the wind out left and right lips

"TUTORIAL PRACTICE"

Okay, maybe that's all

and if you still can't understand the comments below, I'm ready to help
