BREATHING
It is possible to observe that many traditional schools of singing teach breathing as some harrowing, complex event. You've probably heard "sing from your diaphragm," "flex your bottom," "support with your stomach," "expand your back," and so on. All of these concepts set the singer up for unnecessary distraction and tension. Stand up straight and breathe! When you breathe in, the viscera (your belly) falls forward. When you breathe out, it falls back into place. That's it! Here's what it looks like:
CORRECT
Inhale Exhale

INCORRECT
Inhale Exhale

(Too rigid) (Trying to push air out with the rib cage)
POSTURE
It's simple. Stand up straight and relax. Washing your cat is difficult - standing and breathing is easy.
Your posture should not be rigid. If you were to lie flat on your back on the floor, in a comfortable manner, that would also be how good posture looks when you are standing up.
