Whistle Refister/Dual note singing.
Hello all, I have a question. I know one of the guarantees is this: "if I can't teach it, it can't be done"
We know that the whistle register exists, so my question is can this be taught or is it a freak of nature type thing? Mariah C. can sing higher than I can whistle, how is that done?
The next question is this: how do people sing two notes simultaneously? Chester from Linkin Park is know to sing two notes at once. Can this be taught?
NOTE: please know that I am not trying to stir up an unpleasantness; I know it can be hard to determine what someone's attitude or agenda is while reading mere text.
Thank you all kindly (:
