😮 it is incredible! So there’s a lot of elastic energy in a breath! Thanks very much, it is an additional element which reinforces my belief that i am on the right path. Because you know that many teachers say to use air to change pitch but I never understood that! I thought, but I did not understand physically how it could work! Now, with your help, I understand. It is finally logical! Thanks very much to share all those good things.
Cheers, Francis.
