First and foremost, make sure that you are breathing. And when we say “breathe” we mean “breathe properly”. When you inhale, push your stomach outwards. At this point, you should feel your diaphragm rise. For those who don’t know, a diaphragm is the muscle that is located just above your stomach. This will allow you to take in more air and this extra air is what will allow you to hold pitch and sing more smoothly.
