Breathing and Vowel Pitch

I think there are two items that the current singer does not address properly: Breathing and Vowel Pitch. It is an air system. By that I mean, your car runs on gas, the singing voice runs on air. You would not go on a trip with a half tank of gas. There is vocal chord pitch, which is a mind thing and then there is a shape that you are going to put that air and vocal chord pitch thru. The two pitches must be in alinement. What do you think?
