In teaching thousands of singers around the world, I have never met one who did not have more potential range than they knew and were using. Sometimes factors such as smoking cigarettes or marijuana, heavy drug or alcohol use, etc. can limit range expansion. However, in the absence of these inhibitors, an increase of range can be achieved with knowledge, understanding and the right exercises. With that in mind, let’s explore what you need to do to expand your vocal range.
How the Voice Works
Usually when you refer to “my voice” you’re thinking of the way you sound rather than the physical parts of your instrument. It’s important to know that the way you sound and the size of your range is the result of small natural muscle movements inside your body. Of particular interest are the muscles in your throat, back of mouth and larynx (voice box). The better conditioned and limber these muscles are and the less you interfere with their natural movements, the better you sound.
The sounds of your voice are varying degrees of vibrations of your vocal folds (they are actually folds, not vocal cords). Your vocal folds are located in the front of the throat just behind the Adam’s Apple. They lie horizontally across the inside of your breathing tube. In order for your vocal folds to produce different pitches for you, they must vibrate at different speeds.
Breathing Versus Vocal Sound
For breathing, the folds are relaxed open and air passes freely between them. To demonstrate, put your feet flat on the floor. Put them together side by side. Now keep your toes together and open your heels. You’ll see a wedge-like space between them. This is somewhat how your vocal folds are positioned during breathing. Your toes together represent your Adam’s apple. Looking down at your feet is like looking down through your head and throat and seeing the tops of your vocal folds inside your larynx. Now keep your toes together and close your heels. Your feet should be touching side by side. For singing or speaking, the back ends (your heels) automatically close and the rims of the folds lie next to each other.
This is so the air can make them vibrate. The air stream must come under them, support their particular position and stimulate their vibration. For different pitches, the folds stretch and thin. Different lengths of the folds vibrate appropriately. This is similar to how you would fret a string on a guitar, shortening it to produce higher pitches. The muscles of the vocal folds are able to do this automatically, as long as they are conditioned properly and nothing hinders them, such as too forceful an air stream or throat muscle tension.
But who wants to have to think about breathing while singing?! The best breath support would be one which automatically provided just the right amount of air for each pitch you sing without causing tension. This type of breath support is an integral part of The Deva Method.
In subsequent blog posts we’ll cover the five primary reasons for throat muscle tension, which when resolved result in vocal range expansion.
