When you walk uphill or down, especially on grass, the knees bend to prevent your falling. You’re moving downhill, we might say, in a portable squat. Go find a grassy hill and try that. I’ll wait…. Now, having experienced that, bring that dynamic to your standing. Bend your knees—send them forward—and free your neck to allow your torso to cantilever forward and skyward at about a 30 degree angle at the joint of leg and torso, your derriere going back as if to a chair behind you. That’s position of mechanical advantage the way you’ve been taught to lift. Remain there a bit. Position of mechanical advantage frees the hips, the ankles. It makes of the self a grounded little resonator. In this transitionary position, now, strum the body. Utter a great Boh! or Stop! or Heh! You may discover the sound of your body unfettered by worry and judgment, the visceral basis of your singing. That can be a very big thing.
