The fullest ambit of motion

In order to increase the efficiency of the movement of any body part; for a body part to be free to move in one particular plane of motion; it should be free to move in all possible planes.
If, for example, the fingers desire to move vertically as part of pushing down or releasing a key, they should also be free to move laterally as well. they should also be capable of rotating around their long axis from finger tip to third knuckle. the tips of the fingers should be capable of tracing out the circumference of a circle. in addition to flexing they should be capable of ‘un’-flexing, brushing the keys backwards away from the rest of the
hand. Any motion of the finger whose primary aim is to depress a key, should be the dominant motion within a harmony of motions that includes all the others just listed. Isolating any one of these motions and then reincorporating into the general motion of the finger has the effect making the finger more alive, more capable of subtleties in its motion. When all motions are possible and immanent, the one preferred motion occurs in a more organic fashion. By restricting any one plane of motion in the finger in order to dwell on or emphasize one particular time of motion has the opposite effect
Other examples are the wrist, the forearm, the elbow, etc. In the case of the wrist, for instance, under the influence of the faintest prompting, should be capable of moving up and down, left to right, or make circles. More about the ambits of the wrist and other parts of the body in a future blog.
