Gentlemen: I discovered another secret and you tell me if it works for you. Do
you have problems on tags or just long passages where you don't seem to have
enough oxygen to make it through the phrase?
Close your mouth and pull the air in
through your nose only, the warm air warmed by your nose that you use
for singing will let you belt a tag out or make it through a phrase like
nobody's business!

What say you? George Luken
