How to sing really fast without running out of breath?

I can not sing at all ?!!?

• How to sing without running out of breath and any breathing techniques? And how to sing in tune ?

• Answer:

  my singing teacher says to always make sure your mouth goes north and south when you sing. It makes you voice sound better. And also if you don't add any Rs to the words with R it sound much better. For example instead of saying Bear, say bea. I hope this helps!
