Being able to read another person's facial expression and body language in order to assess social cues seems to be to some extent contingent on being able to read oneself. The process of reading another is full of mine fields and we are all familiar with misunderstanding and being misunderstood. So we clarify with questions and through conversation we gather some general sense of what another may be feeling.
Apparently having your face injected with botox means that your face may not be able to represent you authentically. It seems to follow that if you cannot express yourself authentically with your facial expressions then you may not be able to read others facial expressions...there is some sort of sense of vibration missing.
So I am thinking that there is a parallel here to the singing voice...now that is a leap I know..but think about what the voice really is: It is a vibration. The vibration of my voice does not just arrive in your ears.
It comes towards you as a vibration of the air and some of it arrives in your ears
Ears aren't giant funnels to scoop up all sounds...they just take in what they can. But the sound of me to you comes in a much broader spectrum and so the vibrations from my voice enter your body in many ways.
When you stand before me and sing, your voice is read by my whole body. This explains why as a singing teacher I have developed a strong empathy for the way that my singing pupils are using their voice.
Hour after hour I experience my own and other peoples vocal sound waves.
I know what my vocal sounds mean and how to adjust what I am doing to free up my voice.
I do get a sense of how pupils are using their voices.
Last week my pupil had a frog in her throat and I cleared mine to help!!
