A video response on a "pig squeal challenge" by 'Blade376' see: http://www.youtube.com/watch?v=8F_Sd2uHIOQ
Three different ways of grunting.
There is no "how to do it" in grunting and squealing.
Just practice..People tell you to inhale to squeal?
B**lsh*t!..I EXhale..so it's everyone to do it his or her way.
It has nothing to do with the way you breathe or inhaling or exhaling..
It's just bending your voice and practice your throat.
Or you can...Or you can't do it.
It's THAT simple.
Just try to imitate some voices you hear on a cd and keep practicing.
Thats ALL there's to it!
