Belt technique is controversial in the voice world. I grew up with the belief that if I did anything other than sing in head voice that I *would* destroy my voice, and even in 2018, I meet students and voice teachers all the time who share that sentiment. The truth is, belting can be dangerous for your voice if you do it with bad technique or if you force yourself to do it when your voice isn’t in shape for it. But if you learn how to do it in a healthy way and listen to your body when your voice isn’t up for it, all will be well. For better or for worse, belting is an indispensable skill in most commercial styles of music, and there’s really no substitute. If you’re ready to take your singing to the next level, here are some important tips for learning to belt in a sustainable, healthy way.
1. Set the Foundation
Great support is absolutely crucial for healthy belting. Think of it this way. When you’re backpacking, you strap your pack on with a variety of straps to distribute the pressure around your body. That way the full force of the backpack isn’t crushing your shoulders. When you belt, you don’t want those tiny laryngeal muscles doing all the work.
Stand up straight. Your back should feel wide and long, and if someone were to try to push you over, you should be so stable that you could weather it. Your spine should be stacked vertically, and your sternocleidomastoids, that pair of muscles that extend from your chest to the base of your skull, should be at work keeping your neck in line with your torso.
When you have a stable base, everything from your breath control muscles (the diaphragm and external intercostals in particular) to the small muscles in your vocal tract can work more efficiently.
2. Use Very Little Air
One of the biggest mistakes newbie belters make is using more air than they need. When you hear a big voice, it may sound like the way to recreate it is to take a giant breath and shove all that air out at once. What this actually does though is force your vocal folds to work significantly harder. Part of the chesty sound belters achieve is created by a longer closed phase. This means that your vocal folds stay together longer during each cycle of vibration. If you use too much air, your vocal folds will have to work very hard to stay shut.
When you belt, don’t take in too much air. Use a relaxed inhalation, and then hold most of the air back when you create your sound. Keep your ribcage expanded so that your diaphragm stays in a low position instead of rising quickly and crowding your lungs. Your exhalation as you sing should be extremely slow and controlled, even more so than in classical singing.
3. Crush the Constriction
One of the biggest culprits in injuring your voice when you belt is the constriction of your false vocal folds, the muscular folds that sit above your vocal folds in your larynx. Your false vocal folds have a tendency to constrict when your body thinks it’s under duress. Constriction is triggered by a variety of things, from heavy labor to anxiety. When your false vocal folds are constricted, you’ll feel your throat get tight and close up.
To retract your false vocal folds, in other words, to open your throat, you can use a variety of visual cues. Visualize inhaling and smelling a rose; laugh silently and hold the position; or pull your ears apart. You can test whether your folds are retracted by covering your ears and breathing. When you can no longer hear your breath, your false vocal folds are retracted.
Keeping your throat open like this is by far the safest way to belt.
4. Learn to Twang
You know that hooty, woofy sound you hear when someone does a bad imitation of an opera singer? Well that ain’t gonna do it. You need a boat-load of forward resonance to make this happen. Try cackling like a witch, quacking like a duck, or saying “nya nya nya” like a bratty kid. You don’t have to be belting yet, but you should feel an extreme narrow, pointed quality to your sound. This is often called twang and is the result of your aryepiglottic sphincter (a tube above your true and false vocal folds) narrowing.
5. Don’t Be Afraid
It may seem contradictory, but the less afraid of belting you are when you do it, the healthier it’ll be. Fear causes tension and constriction, when what you want is freedom. Try fearlessly yelling, “yay!” With a lot of excitement in your voice. Not a trebly, tepid “yay!” A “yay” that someone could hear across a crowded room that’d cause them to smile. There shouldn’t be any real pushing, and it’ll quickly become clear how easy this can be if you let it.
