Oh, ww, I've listened to this for quite a long time but still I can just do it a little - i.e. not worth mentioning. But thank you for at least being able to understand what I mean.

It's some really interesting aspect of singing. How many of those teachers teach it? You can kind of pre-program your voice and then run that program by somehow hitting a function key. Great feature of computers. Why is it something between neglected and forbidden when it comes to singing?
