How do I clear my voice to sing loudly when needed?
Sometimes we have phlegm on the vocal cords as a result of allergies or post nasal drip. Conditions such as acid reflux can also affect vocal quality and volume. The vocal cords might be swollen or have a tiny burst blood vessel that might have been caused by speaking or singing too loudly with an unsupported vocal technique. In any case, you should avoid “clearing the throat” as it brings the cords together in a harsh way and can make matters worse.
The first step is always to see a doctor and determine what is causing the voice to be unclear. Once you determine the health care needs of your instrument, work with a voice specialist. If you feel there is a resistance (something blocking the sound) there may be a tendancy to push against it in an effort to clear the voice. This stresses the instrument. Instead, you need to bring the vocal cords together in the most refined way possible and to sing a pure thread of tone.
Once this precise phonation is established, use the resonators to create volume. Your loud voice should feel easy and effortless in the throat because you are using such great strength in your torso to support it; if there is any strain you need to work with a coach.
If you have developed a pattern of singing with strain or excess air, it takes time and practice to undo that reflex and replace it with a new pattern so . . . be patient and wise. Loud singing can damage the voice when it is not done properly.
