4.3 Vocal pressure and vocal straining

Observing the behaviour of the singer while singing reveals some kinds of vocal constrictions: constricted body, neck, arms, and lower jaw. Other errors can be heard in the sound of the voice itself: constrictions of the tongue and the muscles of the oropharyngeal channel. Constriction of the body can be removed with a correct posture of the singer's corps. You should stand up straight, keep your head in the way that the neck and the spine create a straight line without kinks (don't throw back your head back and do not tilt forward heavily), slightly bend your lumbar section, your shoulders should be deployed, slightly raise your chest, arms hanging loosely alongside the body. It is advisable to walk a little while singing, do small tilts, swivel your neck. These lightweight, small-amplitude movements of the body will help to remove constrictions, and it will not affect the voice building if done correctly.

Constriction of the lower jaw and the tongue affects the voice building seriously. In this case, the sound becomes strained, dull, thrown back; adding the airflow under the ligament does the upward movement. This error can be eliminated if the teacher explains the functioning of the jaw, illustrating it, as well as by doing singing exercises to "A", but also by doing exercises with alternating of A and I vowels.

The constriction (in other words, the same "throaty sound") sound depends on the glottis malfunction, the closure of which takes too long. In this case, pass to the aspirate sound attack and do a gradual transition to a soft attack. For removal of the constriction it is recommended to master the technique of air covering, as well as singing on "OU" and "O". Falsetto singing is helpful with male voices, because doing that kind singing the folds do not come fully close leaving a slit between them.
