Stand tall with your neck straight and your head held high. Open your jaw slightly to reduce tension. Relax your shoulders by placing them slightly back. Stand with your feet spread shoulder-length apart. You may sit after you have developed the proper posture.
Breathe in from your diaphragm by expanding your ribcage and taking air in to the stomach and sides.
Feel your vocal cords vibrate when you sing and aim for a steady stream of air to keep your vocal cords vibrate evenly. Release any tension in your body while you sing. Tension will prevent your vocal cords from vibrating freely and reduce the quality of your tone.
Practice a five-note musical scale to increase your vocal tone. Women will start on middle C and men begin the octave below. Sing the first five notes of a major scale ascending and then descending. The whole time, keep your stomach firm and airflow consistent; as you move toward the higher notes slightly increase the airflow.
