Improvising voice in Vibhadrasana II (Warrior II) posture. 

I am exploring: 

Facial Tention/ Breathing/Pitch/Articulation.

I am experiencing:

Relaxed jaw, lips, tongue, teeth/deep breathing/low, middle and head voice singing rates/relaxation of facial muscles and muscular awareness. 

I am discovering:

Opening the hips and balancing the sacrum and pelvic area correlates to deep breathing, great vibration and improved quality of the tone of the voice (especially the middle voice).
