How to whistle??
 

There are really good song in which artist whistles and it sounds awesome. I don't know how to whistle. How to practice that?? Any ideas and recommendation how to do that??

Come up with a tune and whistle along to it. Purse your lips and push the sound through.

Watch people whistle and emulate them. Sometimes these kind of tricks-of-the-trade can take a bit of perseverance and stubbornness to make happen (like rolling your R's). You can look up guides online, then practice at least 10 min a day (can people whistle for an hour? o.o)

It might come out as you just blowing air for a while. That's okay. Baby steps will lead to success.

can you recommend me some articles or websites online?? Yeah i did some searching and found some but still if you know a real better tutorial on the net...
