i would realy be intrested in jamies answear as well, cause the voiceteacher i asked is realy good! the best one ive ever been able to meet in person.
Dunno what the word for the chordfunction she used.

But she stated that atleast, and i asked her about techniques such as inward breathing to produce the sound hence learning the chord tightness and be able to produce such sounds inwards.
well she replied anyways that inward breathing could be harmful due to that the chords does the process the other way around.

She herself had a very nice whistle and she was connected all they way up from the bottom to the top of her whistles.
But as you said not so much research has been done on this,thats why i ask on this forum. Everyone seams to be telling diffrent storys :P

What is this inward breathing you're talking about? I can't imagine doing any kind of inward breathing while in whistle -- that would be counteractive to doing things correctly.

IMO, I feel this stuff with the whistle register is the same as situations where teachers tell basses that they won't be able to sing high unless in falsetto. It's just a matter of understanding the vocal apparatus and training things properly. IMO, if you can do the whistle notes (correctly), it's a very good indicator that your voice is in tip top shape, because your cords have to be in really good condition to do them well. (Note, that there is a difference between just hitting a whistle note and actually doing it well.)

A lot of people clamp the throat shit and attempt to inhale which will cause the cords to unbcontrollably whistle. I used to be really good at that version but suck now. It's just a cheaters way to whistle OR a way for a singer to begin to learn and understand what is going on. I truly believe that ANYONE can learn to do a whistle tone. Not everyone will sound good at it, but with practice, anyone can develop some incredible high notes to add to their songs. It occurs when the cords are dampened so close towards the front that only a small amount of air vibrates the tiniest part of cord, like blowing on a blade of grass to make it whistle. So if you want to whistle, by all means don't give up because it can happen.

"A lot of people clamp the throat shit"

Ewww, Jaime.

I've found that it's easier to whistle-sing if you kind of approach it like a screech, with very little air in your lungs. Too much air, and it becomes middle register.

Oh yeah, and don't attempt a whistle sound before warming up.

Must have been a Freudian slip. I dunno why in the world I put that word in there. I don't even know what word I was trying to put there. Mybe I was thinking about the Power Push, haha. So please excusre my language, that was a mis-print:(
