Many people, especially women, breathe quite superficially. We are told to hold in our tummies, as we do not want to look fat. This shallow breathing does not help us to relax, let alone sing well.
So let’s look at a way to lower your breathing: take slow and relaxed breaths. Lay your hand on your chest, aim your breathing in the direction of your hand. Move your hand slowly, step-by-step, downwards and each time you move your hand you continue to direct your breathing towards your hand. Move downwards until you have your hand on your belly and you feel your belly rise with your hand when you breathe in. Now continue to keep breathing low for a while. Mision accomplished!
