Finding A Balance Point

A balance point or pivot point to regulate two different motions

…so there were these two giants, and they were sitting on the ends of a very long see-saw.  And the first one said to the other: “been to any good piano recitals lately?”

Whenever any two points in the body happen to be moving at the same time,  there exists the possibility of coordinating these motions.  There is a simple way of bringing the two motions into balance with each other.  The way it’s done is through a mechanism analogous to a see-saw.  The common, reciprocal motion of the people or objects positioned at the two ends of the see-saw plank, bring these two into a controlled relationship with each other.

The two points of the body can be near each other (in the same hand, in the same finger) or further from each other (one hand with the other, a shoulder with an elbow) or still more distant (a hand and a foot, a shoulder and a finger, the buttocks and the wrists), etc., etc..

Neither of the two points on the body need to be at anatomical points of articulation.  They can be any two randomly chosen locations on the body, for instance points chosen that are midway through the length of a bone and not just at the joints at the ends of the bone.

Depending on how randomly the points are chosen, at first, though we are aware that two parts of the body are both in motion at the same time, we may assume that one motion is independent of the other.  If there is to be a relation between the two motions the two have to be separately executed, and then there should be additional eye to bringing them some sort of relation with the other.

What we want though is direct connection between the two body parts, a pre-established harmony, not a relationship that is engineered after we note the existence of the two motions.

There is an obvious advantage to dealing with one automatic correlation than two separate motions that we are additionally trying to coordinate.

Key to establishing this relation is the concept of a balance point: the finding of some point in the body, somewhere between the two body parts, which can act as a fulcrum, or coordinator, of the actions that would be brought into harmony.  This balance point need not even be within the body.

Consider reciprocal motions occurring between two adjacent fingers, such that as one finger goes down the other goes up.  And have it repeat cyclically.

If we connect the tips of the two fingers with an imaginary ‘beam’, and if half way across the beam we imagine placing a fulcrum or pivot point, we will have created an imaginary, very small sized spanning and filling the space between the finger tips. The two fingers are now like two people sitting on the opposite ends of the see-saw.  As we move the fingers reciprocally, we have the new option of visualizing the action occurring not at two different places at the same time, but only in one place.

Wherever the balance point is located, we can conceive of a shunt or connecting member that runs through the fulcrum as well as the two body parts that are to be linked.  And, as in the above case of the two fingers, to regulate the two motions of the two parts, it is only a matter of shifting our awareness away from the one or the other part, and instead into the real or imagined connecting member that possesses a center of balance where we experience both motions simultaneously.  We are no longer thinking about moving the two fingers, we moving the common connecting part.

Both end parts partake of the same overall motion.  Moreover each of the original parts find that their motion is enhanced by the motion of the other because of the regulatory beam.  The two, original, separate motions have combined synergistically.  No longer are we trying to regulate the actions of two different fingers or parts, by seeking to put them into balance.  The balance is automatic because they are just the two ends of a single motion.

We can further extend this image in our imagination.  Let the length of the two halves of the beam that connect the two parts extend beyond each part.  The beam is made longer, the two original parts are no longer at the ends.  Now at the ends of the newly expanded see-saw beam, we imagine two large people sitting down.   And if we extend the beam still further, to activate the see-saw we would require two imaginary giants working on pushing up and down at the extended ends.  In this imaginary situation the relative motion of the two original parts becomes supercharged with mechanical energy.
