It is very important what you do with your head when singing. The head should be nice and balanced. The position of the mike is very important when singing so that it doesn't put any pressure on the lungs and the throat area.

its very important what you do with your head. your head should be nice and balanced, so it feels almost like you�ve got a ping pong ball of air on the top here. a flow of air that would have a ping pong ball just bouncing on the top. so you have a nice long back of your neck and a balanced head. this is very important when singing when using a microphone. if the mic position is too high you�ll pull your head back and it will put tension on your larynx. so ill just show you how that looks. you see this mic position is too high for me. so thats shortening the back of my neck and is making me collapse across the front of my chest and shoulders.
