Find more power in your sound by using these 3 posturing tools:
1. NOSTRILS: Create more space in your nose by puffing out your nostrils and allow the sound to move through that space.
2. EAR LOBES: allow there to be more space between your ears so that there is a sense of "hollow head".
3. SPINE: Lengthen your upper spine (back of your neck) as if you were a marionette on a string and being "pulled up".
Try all three together and compare that feeling to NEUTRAL, where there is no head and neck posture.
