There is a common misconception that there are two discrete vocal registers, “head register” and “chest register.” The truth is, there are actually four vocal registers, but only one of them is used in everyday singing—the modal register. Modal voice is the vocal register used most frequently in speech and singing in most languages. It is also the term used in linguistics for the most common phonation (or voicing) of vowels.
The term “modal” refers to the resonant mode of vocal cords; that is, the optimal combination of airflow and glottal tension that yields maximum vibration. Belief in this disconnected head and chest register is dangerous; the implication is there are only two separate, mutually-exclusive modes your voice can occupy—head and chest—which you can flip on and off like you would a light switch. This makes it difficult to feel and manipulate your voice, because that’s not how it actually works. There is a continuum between chest voice, middle voice, and head voice, and the terms refer not to separate registers, but to where you predominantly feel your voice resonating in your body.
THE VOCAL INSTRUMENT AND RESONANCE
Vocal resonance is the process by which sound is intensified or “colored” after leaving the vocal cords, but before leaving the body. Our unique voices are not only a product of the thickness and length of our vocal cords, but also, the size and shape of surrounding structures around the vocal tract. There are a number of structures in your body that resonate when you sing, including your chest, larynx, pharynx, oral cavity, nasal cavity, and sinuses.
Notice that these structures range as low as your ribcage, and as high as the top of your face. The only structures you can actually consciously manipulate are your throat, mouth, and diaphragm, and this then affects the rest of the resonators. Head voice, chest voice, and middle voice simply refer to where you feel the majority of resonance when you sing.
When you sing in your “head voice” it means you should feel vibration around the upper half of your face, because, at that moment, the predominant resonator is your sinuses. This doesn’t mean the other vocal structures aren’t resonating. It means that more resonance is occurring in your sinuses than anywhere else.
When you sing in your “middle voice” you should feel more vibration around the lower half of your face, chin, and upper neck. What you are primarily feeling is your hard palate resonating, but again, this doesn’t mean the remaining structures, including your chest and sinuses aren’t vibrating sympathetically.
When you sing in your “chest voice” you should feel more vibration around your lower neck, and sternum. If you want to know what this feels like, talk in your regular speaking voice, and put your hand in the middle of your chest. It’s vibrating.
THE CONTINUUM OF YOUR VOICE
The three “voices” form a spectrum rather than discrete vocal modes. Your voice should almost always mix the three resonance areas, with one area taking the lead over the others. So that’s why you’ll hear “sing with more chest voice,” but you’ll never hear, “switch into your chest register.” Your voice as a spectrum means that you can eliminate your “vocal breaks” with practice, by working to seamlessly mix your resonance zones.
In Italian means ‘a little false.’ A method of voice production, usually used by male singers, to sing notes higher than their normal range, resulting from a change in the way the vocal cords are vibrated. It is produced with only the edges of the vocal cords that are stretched open rather than using the full cord.
There is no better way to get familiar with your voice than to experiment. We could do this a thousand times, but if you can’t feel what you are doing to reproduce it, we’re wasting our time. Your vocal tract is an incredibly complicated place, with almost endless ways to sing any given pitch.
- Hum a note, and siren it up and down in pitch. Close your eyes. Do you feel the vibration moving up and down the front of your body?
- Try doing the same thing on different vowel sounds. Does “ee” resonate differently than “oo” or “ah”?
- What happens if you pretend to yawn while singing a note?
- What happens if you try to buzz like a bee while singing a note?
- Try playing around with releasing a lot of air as you sing, and then a little.
