3. The effect of breath on voice and speech
The voice is responsive to emotions and sometimes gets 'blocked', which can prevent or hinder the expression of a range of feelings.
When under stress an individual's breathing pattern will change. When your muscles are tense you cannot use your lungs to their full capacity. When someone is frightened or nervous, a common symptom is tension in the neck and shoulders. This occurs because, when under pressure, we tend to breath faster. This means we inhale plenty of air, but there is not enough time to exhale fully and relax, so we do not get the full benefit.
By using full lung capacity the breath will support the voice and the voice will become richer, fuller and stronger. This will benefit individuals who have a small voice and who worry that they cannot be heard when speaking to a group of people. Volume is controlled in the abdomen not in the throat, so breathing to full strength will allow for greater control of the voice.
Breathing deeply and rhythmically has a calming and therapeutic effect as it releases tension and promotes relaxation. People who are relaxed are more balanced, receptive and confident. It is no coincidence that many religions use rhythmic breathing techniques such as meditation, yoga and silent contemplation, and vocal release in the form of chants, mantras or hymn singing as aids to their devotions. By easing physical tension, mental stress decreases and the mind is effectively freed to follow creative pursuits.
