Breathing
The magic that I work with voices is built on a fundamental rhythm: the movements of the body as you inhale and exhale. Breathing smoothly and deeply works wonders for the body in general. It gives you more energy. It can center and calm your mind. And it will give your voice power and consistency. Once you learn to breathe as calmly and steadily as a child does, you are on your way to fabulous vocal reaches.
So how's your breathing? Let's find out right now.
Stand comfortably in front of a mirror and take a deep breath, inhaling through your nose. Fill up your lungs as completely as you can, then blow the air slowly out through your mouth. Take a mental snapshot of what you just saw and felt. What parts of your body were involved? What moved? How did it feel? The details are important here, so really focus on what you're doing. Breathe in through your nose, fill up your lungs, breathe out. We're all born knowing how to do this perfectly. But how easily we forget. To the smooth in-and-out movement of natural breathing, we add bells and whistles, superchargers, and huge dollops of effort.
When I stand in front of a group of new students and ask them to take a deep breath, giving them the same instructions I just gave you, amazing things happen. Chests puff up, and all over the room, shoulders pop up like bread from a toaster. Here and there, I'll see an occasional Buddha belly, from a person who's been told in the past that deep breathing involves filling up the lower abdomen. There's a strong sense of people actively pushing their bodies open to make space for more air, as though they're pulling on the sides of an empty balloon and holding them apart to make room for more breath.
The exhale is sometimes very forceful, another powerful push, as though they're trying to give birth to a beautiful sound by putting all their strength behind it. You can sometimes see the tension in their faces as they contract their stomach muscles to propel the air out of their lungs.
Does this picture look or feel familiar? Did you notice the toaster effect with your shoulders when you inhaled? Did you feel yourself actively pushing your ribs apart and trying to make your chest larger? How was the exhale? Did you tighten your stomach to get the last bit of air out and keep the stream strong?
The funny thing is, in breathing, there's no extra credit for putting all your will, effort and muscle into getting it right. In fact, all those elements get in the way. Forcing and pushing your breath is a bit like tap dancing on a five-mile hike. You expend a lot of energy, feel like you're giving it your all--and wind up way too exhausted to finish your speech or song with the same power you had when you started. Breathing this way is exhausting, and it wreaks havoc with your stamina. But solid, effective diaphragmatic breathing is just the opposite. It isn't flashy. When you're doing it, air glides easily in and out. And you can do it forever.
I'd like to show you how to strip off the layers of unconscious habits and misguided techniques that stand between you and perfect diaphragmatic breathing, that sheathed-in-mystery process that so many teachers have made complicated over the years. Breathing, as they say in California, is a Zen thing to experience: We have to allow it to happen instead of forcing it. We're meant to float through this kind of breathing ,instead of turning it into a grueling, athletic butterfly stroke. By paying attention to when it gets difficult, or when it seems to take special effort, you'll be able to relax and let the breathing be steady, smooth, and even, the perfect foundation for beautiful speech and singing.

1 Drink as much water as you can.
There are two holes in the back part of your throat–one where the food and water passes, and the other for air. When you drink, the water goes down the liquid hole. The problem is, the vocal cords live down the air hole. It is actually impossible to drink water directly to the cords. So, you need to have so much water in your system that the bloodstream carries it to there. To do that you should drink about one half of a gallon of pure water every day.
2 Tea with honey and lemon is a bad idea.
Sorry mom, but, if the tea has caffeine in it, that unnecessarily speeds up the production of mucous and gives you too much phlegm. Then, the tea is usually too hot and that makes the vocal cords change in size the temperature of liquid can change the size and shape of tissues it comes in contact with. Haven't you noticed your fingers look like prunes when you take a long hot bath? Then, the lemon is citrus which makes you salivate extra, which also makes too much phlegm. And finally, the honey is so thick it causes moisture problems too.
3 Stop Smoking
When you inhale the cigarette smoke passes directly through the vocal cords and dries up a lot of the natural moisture they need to function.
4 Learn Diaphragmatic Breathing
It is very easy and much healthier for the body. Just put your hand on your stomach where your belly button is. When you inhale, pretend that you have a balloon in there and let it expand. When you exhale, let your stomach fall back to its normal position. It's no more difficult than that.
5 Stop tightening your stomach
Too many people have heard the word support and think that it is simply creating pressure in your stomach that somehow helps push the sound out bigger and better. The truth is, when you lock your stomach muscles, you are actually stopping the air from getting back out of your body and making beautiful noises. The key is to relax your stomach muscles and create no pressure at all.
6 Warm up your voice
Use a few minutes of vocal exercises every day. A runner would never start the race without stretching before. Why not give the voice a bit of stretching.
7 No whispering
When you whisper, you send a tremendous amount of extra air to the cords which makes them dry and irritated. This is actually worse than screaming and shouting.
8 Use melody
When you sing a song the melody is important. Why is it that most people are singing boring songs. They stay on one note, they have no interesting dynamics, and they bore the listener. I say, pretend you are singing while you are speaking. Move it around, shake it up, swoop, dive, soar. Let your voice be as interesting as you are.
9 Drop your jaw
Most people simply do not open their mouths enough to let the sound come out unobstructed. I do not mean that you should smile and go very wide. I want you to simply drop your jaw down a bit and not keep your teeth so close together. This will send more sound into the cheek area where it will bounce around and come out more full and resonant.
10 Voice lessons are not about talent.
Every time we open our mouths to speak or sing we are affecting ourselves and the people hearing us. By opening up your voice to it's greatest possibilities, you will experience positive changes both physically and emotionally. Change the way you sound and enjoy the success it will bring to you.
