im having trouble with the oo - oh - ah, ee - ih - eh and all the others..
I find it hard to have vibrato on the start and second vowel, though it is easer to put vibrato on the last..
Is there any method to make it easier???
When I do it in a opera kind of way it works better.
Is it okay to just do it the opera way? Or should I keep it more "clean"?
