Telling the group of this particular irrational fear over and over, what is that, I don't know nor is that very fascinating to me at this stage of life.
Straight. Strait is quite another word.There was like this serious strait faced discussion going on.
Yeah, it's a question of what instrument do you have to work with, which I related to bore size (do something mature with that one, now, lol) and resultant timbre and went a little bit into socialization and gender as constructed vs the physical limitation. It seems like 'formants' was already mentioned, but it's a matter of a 'correct' formant such as in Cubase's pitch shift dialog.
Chances are not very good for a grown man to achieve it unless there were certain factors which did not move totally in the direction of a physical male. Which is where we can bring in 'countertenor' and a somewhat prevalent notion at one time, of castration before it's too late in order to preserve a certain quality of timbre and affect.
There are countertenors today which maintain a certain mystery of voice quality...
But it's only suitable really for a certain kind of room, yeah? Your problem.
