Breathing and vocal exercises are essential in warming up your voice before singing. Singing from your diaphragm is just one part of proper singing technique, and needs to be combined with other good practices. Anytime before you start singing for a long period of time, you should:  Take a long, deep breath and hold it for a few seconds then release it slowly. As you breathe in, raise your arms until your hands touch each other. Then put your arms down slowly while you breathe out. Do these 3-5 times. Start with the lowest note that you can sing and start getting higher until you reach the highest note you can sing, without straining. Don't rush. The slower, the better. This exercise helps to control your breathing and warm up your vocal chords for singing. When singing with your diaphragm, you are taking larger, fuller breaths. Doing this requires perfect posture. Keep your back very straight, your shoulders rolled back, and focus on keeping them still as you breathe to give your voice and your breath the best space possible.  Because your diaphragm is right below your rib cage, which encompasses your lungs, slouching pushes your ribs into your lungs and doesn't allow for the downward expansion necessary to get a good breath. If you're tense while maintaining the correct posture, let gravity help you out. Stand against a wall so the back of your head, shoulders, and bottom rest against the wall. Notice how free your diaphragm feels while you're singing! Look in a mirror while you force a yawn, looking and feeling the openness in your throat. This needs to happen while you sing, but as relaxed and loose as possible. To allow the air to flow more freely and naturally from your diaphragm through your body, you need to practice singing with an open throat. Pretend you've got a marshmallow the size of a baseball in your throat that's stretching it open. Practice singing runs of notes while your throat is open. It might take a while to get the notes as strong as you're used to, but it's an important part of retraining your voice to stay strong. Think about your voice as if it is broken into two separate, but linked parts. Your high notes are in what is called your head voice and your low notes are in your chest voice. When you sing low notes, try not to sing as loud as you sing high notes, because this may result in your note being higher that it is supposed to be. To make full, rounded sound in each of your voices requires singing from the diaphragm, but learning to distinguish these two voices and move between them will help with note placement. Use your breathing exercises regularly to get used to the sensation of moving between your two voices. Try singing intervals to jump back and forth between the two different voices and strengthen your transitions. Hard consonants often become inaudible when singing. Try repeating a consonant phrase like "The tip of the tongue and the teeth and the lips." Sing the phrase over and over on a single note, until every word can be sung clearly with full breath support from your diaphragm.
