Most singing teachers agree that each males and females have «head voice» as part of their sound. This term applies to the way the vocal cords vibrate and work when we sing high notes. I will go into the mechanics of the vocal cords in another article and in my programs, however for now let’s just understand that strips of membrane in our larynx (adam’s apple) we call vocal cords vibrate in opposition to one another, turning air from our lungs into sound. For lower sounds (the chest voice) the full size or the cords is used for the action. Since higher sounds require smaller, shorter or thinner vibrations (think how a harp looks) the vocal cords should change in shape and dimension with the intention to make high notes.
As we sing higher notes our vocal cords move closer collectively and start to do what’s called the «zipper impact». Higher notes require a smaller opening for the air to undergo, so a small miracle happens because the cord start to «zip» up, leaving a smaller and smaller opening. (Think of what a clothing zipper looks like as it zips up.)
So, whenever you think about it, it should take less air pressure to sing the high notes than the low ones, and it does. For low notes there’s a big opening between the cords the place you’ll be able to pass numerous air through without quite a lot of stress. And the high notes require a smaller opening between the cords. This smaller opening permits less air to pass by means of without stress. When we try to push too much air pressure (quantity) by way of the cords for higher notes we cause them to work too hard resisting the extra air. This produces an excessively-fats, amateurish sound which sounds forced and difficult.
When we sing higher we «really feel» we must work harder to get these notes out. In actual fact, we need to back off some, really feel the sound higher in our head, letting it thin like the higher notes of the piano or guitar.
Try singing a sweeping continuous «ah» or «uh» vowel, starting at your lowest note and «sweeping» or sliding the continual sound up to your highest notes. Notice that you will probably reach some extent when it appears you can go no higher. Lighten your sound there and begin to let it thin and feel higher in your head. Guys, when you go into the falsetto that is OK for now. Let you voice do what it must do. Girls you may probably must move into your head voice at some point. That is ok. Just keep going, attempting not to strain.
Do this exercise often, taking note of how the higher notes feel. Are you pushing and straining, or are you just letting it sweep on up?
