Even if you think you are supporting your voice correctly by pulling your stomach in around your navel, you still risk creating incorrect support. Another form of incorrect support involves pulling the stomach in too strongly and tensing it excessively. This is known as ‘hidden incorrect support’ and is more difficult to detect than standard incorrect support. It is usually detected when a singer contracts the support muscles strongly without achieving any positive results in the voice. With hidden incorrect support, one can usually hear that it causes uncontrolled constriction, and the singer often feels intense pressure in the solar plexus and abdomen. Nowadays, many singers believe that creating support really does require that much force. Despite tensing their abdominal muscles, the sound produced does not match their expectations. In an attempt to strengthen the support even further, the singer continues to increase the pressure. Eventually, they come to the conclusion that the problem may be linked to overdoing the support.
Neither of these two conclusions is correct. There is no support. In fact, what the singer perceives as support has turned into muscular tension, and no matter how much it is intensified, it will not improve the support or the sound. The body has lost control of the diaphragm, which has released most of the air, and the work of the abdominal muscles is futile. Hidden incorrect support feels like a sensation of stiffness in the abdominal area around the navel, just as with incorrect support. The only difference between a concealed poor posture and poor posture is that, with a concealed poor posture, the abdomen around the navel is drawn in.
