After singing for quite a while now ive noticed that theres a light switch of resonance sometimes i have it sometimes i dont. Sometimes when I go its the LAW ahh I can feel the heavy vibration at the top of my mouth it allows me to sing almost anything. Then sometimes I cant get that resonance its just not there usually if i stop singing for a while. Id like to understand the resonating mechanism better. Is there a way to always have it? What would be the best way to unleash the beast within without hurting myself?
