The ear has several functions :
- a function of balance, space-time organization: it ensures body integration, the control of the movements, posture, rhythm, swiftness and fluidity.
- a function of analysis in height, tone, and intensity of the sound
- a function of dynamization of the brain : in particular the high pitches (harmonics) which gives this cortical load.
Moreover the ear is in close connection with the nervous system and the neurovégétative life.
