Icdedturkes hit the nail on the head ,,,,HUFF,,,,,from your gut ,,,do not blow.
Short huffing ,,,huff ,huff,huff = yelp ,yelp , yelp.
How much range in sound can one get ? Just see how much sound you can get . Try to play along with some ol' country & western song or something . By you learning just how much range you can accomplish you'll hear those turkey pitches in that mess and you'll soon figure it out .
Like has been already said ,,,it usually takes a few or even several calls to find the right one .
