My HS Choir director told us to lie down to learn to breathe, as you canNOT do it wrong when on your back. One of the vocal teachers in town says that when you are 'out' of air, to give a little push from your abdomen to get to the rest. It works if you can remember to do it! I find, however that I run out because I do forget to breathe in the right places. If I'm using music I write BIG BREATH! where I'm forgetting, and then it's better...
