Improvising voice in Trikonasana (Triangle) posture.

I am exploring: 

Facial Tention/ Breathing/Pitch/Articulation.

I am experiencing:

No facial tention/easy breathing, chest lightness/easier access to head voice than the low one - both middle and head voice accessible/relaxed jaw and lips and tongue. 

I am discovering:

Stretching the sides of the spine toned my intercostal muscles and created space to my ribs and thoracic area. As a result, there was plenty space for breathing and easy access and management of head voice.
