Make a thorough explanation of posture and stances.

"Neutral stance is the best stance for breathing exercises, here are a few examples"

Defined as your unique sound quality a variety of things go into making it actually work. Here they are as follows: 

• The way you breathe because the air in your lungs vibrates to create sound in your vocal cords 

• Your resonance, being the intensity and quality of the soundwaves from your vocals 

• And your vocal chords itself. Being located in the larynx above your windpipe directly behind your adam’s apple. 

The components of your vocals are: 

Trachea - The trachea is your windpipe. It's the tube that connects your lungs to your throat.   

Pharynx - The pharynx is the throat. It goes up from the larynx and divides into the laryngopharynx (just above the larynx), oropharynx (going into the mouth) and nasopharynx (going into the nose) 

• Esophagus 
  The esophagus is your food pipe. It's just behind the larynx and trachea. Your pharynx carries both air and food/water. The air goes through the larynx and trachea, and food and water go into your esophagus. 

• Spinal column 
  The spinal column is behind the esophagus. You can feel it by pressing the back of your neck. 

Diaphragm 
The diaphragm is underneath the lungs, inside the rib cage. It's shaped like a dome. The diaphragm is your main muscle for controlling respiration 

“ Vocal folds are the same as vocal cords. The two terms refer to the exact same part of the body performing the exact same functions.  “
