OK I will try the exercise.
Mdew so I am am going to sing closed vowels with "pure head voice" and the open ones with a mix (in the high range)? I have been doing that before, before I am really warmed up. One more question, the falsettoish tonal quality of the screams from guys like Rob Halford, Phil Anselmo, Eric Adams and such, does this come over time from practicing the high range alot or is there some kind of vocal effect they are using, because if I am using twang or cry in my mix, it doesn't sound right very often. I know that it is really hard work to get there, I just wasn't sure if I am doing it right, or if there is some other "register" for these really high screams.
Thank you very much for your help
