In order to give yourself a more open voice you need to position your body accordingly. If you are compromising your stance, you are compromising your sound and you will never reach your true vocal potential. So here’s my suggestion…raise both arms high above your head and feel how this position opens your torso and lifts your rib cage off of your diaphragm allowing it to function fully. Then, just simply drop your arms and keep your torso in that lifted position. Try to find a relaxed version of this position and notice how it effects your voice.
