If you now discovered that your doing all of the 4 points in some gradation during singing, don’t feel bad. You’re not unnatural singing in this tight way. All of the things I said above are natural reactions of our body on nerves, fear and tension. These reactions unfortunately just aren’t useful for singing. But they make it hard to relax the jaw on a high pitch because the pitch is feared before it sounds. Please, pretend now to see something shocking and hold your shock. When I do that my fists clench, my abdominals tense, my head goes up, my jaw clenches and my tongue falls back. In singing you have to work against this reaction on some degree.
This doesn’t mean that when you feel your throat tightened, you are always very nervous. It means that there are some built-in habits at work that you need to change through continuous exercises and preferably vocal lessons with a good teacher so you will get the right feedback. In this way the tight feeling will gradually decrease. Read also: why should I take vocal lessons? I hope that this blog gave you a starting point of where to look for making your singing feel nicer.
