The muscles of the chest and waist are freed through a series of motions, the result of which is shown in the ability to toss the body lightly from the hips, as the head is tossed from the waist muscles; and there follows the same gentle involuntary swing of the muscles of the waist which surprises one so pleasantly in the neck muscles after tossing the head, and gives a new realization of what physical freedom is.

In tossing the body the motion must be successive, like running the scale with the vertebrae.

In no motion should the muscles work en masse. The more perfect the co-ordination of muscles in any movement, the more truly each muscle holds its own individuality. This power of freedom in motion should be worked for after once approaching the natural equilibrium. If you rest on your left leg, it pushes your left hip a little farther out, which causes your body to swerve slightly to the right,—and, to keep the balance true, the head again tips to the left a little. Now rise slowly and freely from that to standing on both feet, with body and head erect; then drop on the right foot with the body to left, and head to right. Here again, as in the motions with the spine, there is a great difference in the way they are practised. Their main object is to help the muscles to an independent individual co-ordination, and there should be a new sense of ease and freedom every time we practise it. Hold the chest up, and push yourself erect with the ball of your free foot. The more the weight is thought into the feet the freer the muscles are for action, provided the chest is well raised. The forward and back spinal motion should be taken standing also; and there is a gentle circular motion of the entire body which proves the freedom of all the muscles for natural movement, and is most restful in its result.

The study for free movement in the arms and legs should of course be separate. The law that every part moves from something prior to it, is illustrated exquisitely in the motion of the fingers from the wrist. Here also the individuality of the muscles in their perfect co-ordination is pleasantly illustrated. To gain ease of movement in the fore arm, its motive power must seem to be in the upper arm; the motive power for the entire arm must seem to be centred in the shoulder. When through various exercises a natural co-ordination of the muscles is gained, the arm can be moved in curves from the shoulder, which remind one of a graceful snake; and the balance is so true that the motion seems hardly more than a thought in the amount of effort it takes. Great care should be given to freeing the hands and fingers. Because the hand is in such constant communication with the brain, the tension of the entire body often seems to be reflected there. Sometimes it is even necessary to train the hand to some extent in the earliest lessons.

Exercises for movement in the legs are to free the joints, so that motions may follow one another as in the arm,—the foot from the ankle; the lower leg from the upper leg; the upper leg from the hip; and, as—in the arm, the free action of the joints in the leg comes as we seem to centre the motive power in the hip. There is then the same grace and ease of movement which we gain in the arm, simply because the muscles have their natural equilibrium.

Thus the motive power of the body will seem to be gradually drawn to an imaginary centre in the lower part of the trunk,—which simply means withdrawing superfluous tension from every part. The exercise to help establish this equilibrium is graceful, and not difficult if we take it quietly and easily, using the mind to hold a balance without effort. Raise the right arm diagonally forward, the left leg diagonally back,—the arm must be high up, the foot just off the floor, so that as far as possible you make a direct line from the wrist to the ankle; in this attitude stretch all muscles across the body from left to right slowly and steadily, then relax quite as slowly. Now, be sure your arm and leg are free from all tension, and swing them very slowly, as if they were one piece, to as nearly a horizontal position as they can reach; then slowly pivot round until you bring your arm diagonally back and your leg diagonally forward; still horizontal, pivot again to the starting point; then bring leg down and arm up, always keeping them as in a line, until your foot is again off the floor; then slowly lower your arm and let your foot rest on the floor so that gradually your whole weight rests on that leg, and the other is free to swing up and pivot with the opposite arm. All this must be done slowly and without strain of any kind. The motions which follow in sets are for the better daily working of the body, as well as to establish its freedom. The first set is called the "Big Rhythms," because it takes mainly the rhythmic movement of the larger muscles of the body, and is meant, through movements taken on one foot, to give a true balance in the poise of the body as well as to make habitual the natural co-ordination in the action of all the larger muscles. It is like practising a series of big musical chords to accustom our ears to their harmonies. The second set, named the "Little Rhythms,"—because that is a convenient way of designating it,—is a series meant to include the movement of all the smaller muscles as well as the large ones, and is carried out even to the fingers. The third set is for spring and rapid motion, especially in joints of arms and legs.

Of course having once found the body's natural freedom, the variety of motions is as great as the variety of musical sounds and combinations possible to an instrument which will respond to every tone in the musical scale. It is in opening the way for this natural motion that the exquisite possibilities in motion purely artistic dawn upon us with ever-increasing light. And as in music it is the sonata, the waltz, or the nocturne we must feel, not the mechanical process of our own performance,—so in moving, it is the beautiful, natural harmonies of the muscles, from the big rhythms to all the smaller ones, that we must feel and make others feel, and not the mere mechanical grace of our bodies; and we can move a sonata from the first to the last, changing the time and holding the theme so that the soul will be touched through the eye, as it is through the ear now in music. But, according to the present state of the human body, more than one generation will pass before we reach, or know the beginning of, the highest artistic power of motion. If art is Nature illuminated, one must have some slight appreciation and experience of Nature before attempting her illumination.

The set of motions mentioned can be only very inadequately described in print. But although they are graceful, because they are natural, the first idea in practising them is that they are a means to an end, not an end in themselves. For in the big and little rhythms and the springing motions, in practising them over and over again we are establishing the habit of natural motion, and will carry it more and more into everything we do.

If the work of the brain in muscular exercise were reduced to its minimum, the consequent benefit from all exercise would greatly increase.

A new movement can be learned with facility in proportion to the power for dropping at the time all impressions of previous movements. In training to take every motion easily, after a time the brain-work is relieved, for we move with ease,—that is, with a natural co-ordination of muscles, automatically,—in every known motion; and we lessen very greatly the mental strain, in learning a new movement, by gaining the power to relax entirely at first, and then, out of a free body, choose the muscles needed, and so avoid the nervous strain of useless muscular experiment.
