Avoid titling your head and creating tension when practicing vocals.
Projecting vocals requires learning to sing properly to produce a strong, rich sound. It takes time to develop the strength to sing powerfully. The best way to learn to develop your ability to project your vocals is daily vocal practice with proper technique. Even if you perform in a band and have to contort your body while singing on stage, you should still practice as if you were learning to sing in a classical style. This will improve your ability to sing healthfully and effectively.
Instructions
1. Assume a proper posture. Stand up straight. Imagine that a string is pulling your body up from the top of your head. Your legs should be spaced equally and at a comfortable stance. Don't lean to one side while singing. Your shoulders should be back and tension in your neck should be limited. Find a position in which your entire being feels open and free of tension.
2. Breathe into the diaphragm and use the diaphragm to expel air. Many vocalists breathe into the chest. This will severely limit your ability to project your vocals.
3. Prevent tension in your mouth and neck by singing with proper diction. Diction is the key to getting a penetrating sound to project. If you are mumbling words, or not clearly articulating, the audience will not be able to hear you sing. Diction is simply learning pronounce words properly while singing. Singing and talking do not always require the same pronunciation. Work with a vocal coach if you have trouble with diction.
4. Practice daily for at least 30 to 45 minutes to improve your endurance, but avoid practicing so much that you hurt your voice. There is a fine line between practicing at an acceptable limit and overdoing it. Vocalists have to be especially mindful of their practicing schedule.
