Proprioception is detected via the inner ear and brain--feedback is sent to the brain when changing body position that results in shifting the centre of gravity in relation to the base of support, the feet.
Performers most commonly need to attain, adjust and sometimes regain a posture that allows them to maintain the centre of gravity above the feet, the origin of support in a stationary position.
As stated, one can remain balanced and steady as long as the centre of gravity, the small of the back, lies over the feet.
It is crucial to note that detaching the back from the lower part of the chair can result in losing the fullness of the lower abdomen and the centre of gravity. This in turn produces a lack of balance and tightness of the anal sphincter, back, abdomen, throat and neck.
Given that movements are pervasive and integral parts of both musical perception and production, it is essential to consider how individual flute performers can ensure that the centre of gravity is maintained while they are involved in expressive movements during performance.
On the other hand, the other forward and backward movements, that are commonly prevalent among individuals especially younger flute performers, are generally recognized as responsible for their lack of balance as they cause individuals to go far beyond their centre of gravity and support base.
To maintain the centre of gravity while moving during playing, the pose performance method holds that constant balance and support can be efficiently maintained if the performer actively but gently pushes the little toes against the ground.
They jump up, down, sidewards and in all other directions while they maintain the centre of gravity and support through the small of the back and the forefoot (Romanov, 2002).
In order to analyse an entire linguistic data corpus dialectometrically, the centre of gravity of every area of distribution for every reported response has to be established first.
Apart from the relevant responses the lists contain the centre of gravity, marked specifically on the radiation maps, the map number (an asterisk refers to maps in Viereck -- Ramisch 1991), the map title on which the particular feature appears plus its frequency of occurence.
