Chapter III: Introduction: The Meaning of Design (2)

69. The repetition of a certain shape-motive in a line is not, necessarily, a repetition in the same measure or scale. A repetition of the same shape in the same measure means Measure and Shape-Harmony in the progression. A repetition of the same shape in different measures means Shape-Harmony without Measure-Harmony.

Here we have the repetition of a certain shape in a line, in a progression of measures. That gives us Shape-Harmony and a Harmony of Proportions, without Measure-Harmony.

70. In the repetition of a certain shape-motive in the line, the line may change its direction abruptly or gradually, continuously or alternately, producing a Linear Progression with changes of direction.

In Fig. 79 there is a certain change of direction as we pass from one repetition to the next. In the repetition of the same change of direction, of the same angle of divergence, we have Harmony. If the angles of divergence varied we should have no such Harmony, though we might have Harmony in the repetition of a certain relation of divergences. Any repetition of a certain change or changes of direction in a linear progression gives a Harmony of Directions in the progression.

In this case there is a regular alternation of directions in the repeats. The repeats are drawn first to the right, then up, and the relation of these two directions is then repeated.

71. By inverting the motive of any progression, in single or in double inversion, and repeating the motive together with its inversion, we are able to vary the character of the progression indefinitely.

In this case we have a single inversion of the motive and a repetition of the motive with its inversion. Compare this progression with the one in Fig. 77, where the same motive is repeated without inversion.

Here we have the same motive with a double inversion, the motive with its double inversion being repeated. The inversion gives us Shape-Harmony without Harmony of Attitudes. We have Harmony, however, in a repetition of the relation of two attitudes. These double inversions are more interesting from the point of view of Balance than of Harmony.

THE ORDER OF BALANCE IN LINES

72. We have Balance in a line when one half of it is the single or double inversion of the other half; that is, when there is an equal opposition and consequent equilibrium of attractions in the line. When the axis of the inversion is vertical the balance is symmetrical.

There is Balance in this line because half of it is the single inversion of the other half. The balance is symmetrical because the axis is vertical. The balance, although symmetrical, is not likely to be appreciated, however, because the eye is sure to move along a line upon which there is no better reason for not moving than is found in slight terminal contrasts. The eye is not held at the center when there is nothing to hold the eye on the center. Mark the center in any way and the eye will go to it at once. A mark or accent may be put at the center, or accents, corresponding and equal, may be put at equal distances from the center in opposite directions. The eye will then be held at the center by the force of equal and opposite attractions.

In this case the eye is held at the balance-center of the line by a change of character at that point.

In this case the changes of character are at equal distances, in opposite directions, from the center. The center is marked by a break. The axis being vertical, the balance is a symmetrical one.

73. The appreciation of Balance in a line depends very much upon the attitude in which it is drawn.

In this case the balance in the line itself is just as good as it is in Fig. 85; but the axis of the balance being diagonal, the balance is less distinctly felt. The balance is unsatisfactory because the attitude of the line is one which suggests a falling down to the left. It is the instability of the line which is felt, more than the balance in it.

In this case of double inversion, also, we have balance. The balance is more distinctly felt than it was in Fig. 86. The attitude is one of stability. This balance is neither axial nor symmetrical, but central.

74. A line balances, in a sense, when its inclinations are balanced.

This line may be said to be in balance, as it has no inclinations, either to the right or to the left, to suggest instability. The verticals and the horizontals, being stable, look after themselves perfectly well.

This line has two unbalanced inclinations to the left. It is, therefore, less satisfactory than the line in Fig. 88, from the point of view of Balance.

The two inclinations in this line counteract one another. One inclination toward the left is balanced by a corresponding inclination toward the right.

In this case, also, there is no inclination toward the left which is not balanced by a corresponding inclination toward the right.

In this line, which is composed wholly of inclinations to the right or left, every inclination is balanced, and the line is, therefore, orderly in the sense of Balance; more so, certainly, than it would be if the inclinations were not counteracted. This is the problem of balancing the directions or inclinations of a line.

75. A line having no balance or symmetry in itself may become balanced. The line may be regarded as if it were a series of dots close together. The line is then a relation of positions indicated by dots. It is a composition of attractions corresponding and equal. It is only necessary, then, to find what I have called the center of equilibrium, the balance-center of the attractions, and to indicate that center by a symmetrical inclosure. The line will then become balanced.

Here is a line. To find the center of its attractions it may be considered as if it were a line of dots, like this:—

The principle according to which we find the balance-center is stated on page 23. The balance-center being found, it must be indicated unmistakably. This may be done by means of any symmetrical inclosure which will draw the eye to the center and hold it there.

In this case the balance-center is indicated by a rectangular inclosure. This rectangle is not, however, in harmony of character with the line inclosed by it, which is curved.

In this case the balance-center is indicated by a circle, which, being a curve, is in harmony of character with the inclosed line, which is also a curve. I shall call this Occult Balance to distinguish it from the unmistakable Balance of Symmetry and other comparatively obvious forms of Balance, including the balance of double inversions. As I have said, on page 24, the symmetrical framing must be sufficiently attractive to hold the eye steadily at the center, otherwise it does not serve its purpose.

THE ORDER OF RHYTHM IN LINES

76. The eye, not being held on a vertical axis or on a balance-center, readily follows any suggestion of movement.

In this case there is no intimation of any vertical axis or balance-center. The figure is consequently unstable. There is a sense of movement to the right. This is due, not only to the inclinations to the right, but to the convergences in that direction.

In this case the movement is unmistakably to the left. In such cases we have movement, but no Rhythm.

77. Rhythm requires, not only movement, but the order of regular and marked intervals.

In Fig. 99 we have a line, a linear progression, which gives us the feeling of movement, unmistakably. The movement, which in the motive itself is not rhythmical, becomes rhythmical in its repetition at regular, and in this case equal, intervals. The intervals are marked by the repetitions.

78. It is a question of some interest to decide how many repetitions are required in a Rhythm. In answer to this question I should say three as a rule. A single repetition shows us only one interval, and we do not know whether the succeeding intervals are to be equal or progressive, arithmetically progressive or geometrically progressive. The rhythm is not defined until this question is decided, as it will be by two more repetitions. The measures of the rhythm might take the form of a repeated relation of measures; a repetition, for example, of the measures two, seven, four. In that case the relation of the three measures would have to be repeated at least three times before the character of the rhythm could be appreciated.

79. Any contrariety of movement in the motive is extended, of course, to its repetitions.

In this case, for example, there are convergences and, consequently, movements both up and down. This contrariety of movements is felt through the whole series of repetitions. Other things being equal, I believe the eye moves up more readily than down, so that convergences downward have less effect upon us than corresponding convergences upward.

In this case, by omitting the long vertical line I have diminished the amount of convergence downward. In that way I have given predominance to the upward movement. Instead of altogether omitting the long vertical line, I might have changed its tone from black to gray. That would cause an approximate instead of complete disappearance. It should be remembered that in all these cases the habit of reading comes in to facilitate the movements to the right. It is easier for the eye to move to the right than in any other direction, other things being equal. The movement back to the beginning of another line, which is of course inevitable in reading, produces comparatively little impression upon us, no more than the turning of the page. The habit of reading to the right happens to be our habit. The habit is not universal.

80. Reading repetitions and alternations to the right, always, I, for a long time, regarded such repetitions and alternations as rhythmical, until Professor Mowll raised the question whether it is necessary to read all alternations to the right when there is nothing in the alternations themselves to suggest a movement in one direction rather than another. Why not read them to the left as well as to the right? We at once decided that the movement in a Rhythm must be determined by the character of the Rhythm itself, not by any habit of reading, or any other habit, on our part. It was in that way that we came to regard repetitions and alternations as illustrations of Harmony rather than of Rhythm. Rhythm comes into the Harmony of a Repeated Relation when the relation is one which causes the eye to move in one direction rather than another, and when the movement is carried on from repetition to repetition, from measure to measure.

81. The repetition of a motive at equal intervals, when there is no movement in the motive, gives us no feeling of Rhythm.

In this case, for example, we have a repetition in the line of a certain symmetrical shape. As there is no movement in the shape repeated, there is no Rhythm in the repetition. There is nothing to draw the eye in one direction rather than another. The attractions at one end of the line correspond with the attractions at the other.

82. The feeling of Rhythm may be induced by a regular diminution of measure or scale in the repetitions of the motive and in the intervals in which the repetitions take place.

In this case the shape repeated is still symmetrical, but it is repeated with a gradual diminution of scale and of intervals, by which we are given a feeling of rhythmic movement. The change of scale and of intervals, to induce a sense of rhythmic motion, must be regular. To be regular the change must be in the terms of one or the other of the regular progressions; the arithmetical progression, which proceeds by a certain addition, or the geometrical, which proceeds by a certain multiplication. The question may arise in this case (Fig. 103) whether the movement of the Rhythm is to the right or to the left. I feel, myself, that the movement is to the right. In diminishing the scale of the motive and of the intervals we have, hardly at all, diminished the extent of the tone-contrast in a given angle of vision. See Fig. 41, p. 27, showing the increase of attractions from one visual angle to another. At the same time we come at the right end of the progression to two or more repetitions in the space of one. We have, therefore, established the attraction of a crowding together at the right end of the series. See the passage (p. 43) on the attractiveness of a line. The force of the crowding together of attractions is, I feel, sufficient to cause a movement to the right. It must be remembered, however, that the greater facility of reading to the right is added here to the pull of a greater crowding together of attractions in the same direction, so the movement of the Rhythm in that direction may not be very strong after all. If the direction of any Rhythm is doubtful, the Rhythm itself is doubtful.

83. The feeling of Rhythm may be induced, as I have said, by a gradual increase of the number of attractions from measure to measure, an increase of the extent of tone-contrast.

Increasing the extent of tone-contrast and the number of attractions in the measures of the Rhythm in Fig. 103, we are able to force the eye to follow the series in the direction contrary to the habit of reading, that is to say from right to left.

A decrease in the forces of attraction in connection with a decrease of scale is familiar to us all in the phenomena of perspective. The gradual disappearance of objects in aerial perspective does away with the attraction of a greater crowding together of objects in the distance.

In this case the diminution of scale has been given up and there is no longer any crowding together. There is no chance of this rhythm being read from left to right except by an effort of the will. The increase of attractions toward the left is much more than sufficient to counteract the habit of reading.

84. The force of a gradual coming together of attractions, inducing movement in the direction of such coming together, is noticeable in spiral shapes.

In this case we have a series of straight lines with a constant and equal change of direction to the right, combined with a regular diminution of measures in the length of the lines, this in the terms of an arithmetical progression. The movement is in the direction of concentration and it is distinctly marked in its measures. The movement is therefore rhythmical.

In this case we have a series of straight lines with a constant change of direction to the right; but in this case the changes of measure in the lines are in the terms of a geometrical progression. The direction is the same, the pull of concentration perhaps stronger.

In this Rhythm there is an arithmetical gradation of measures in the changes of direction, both in the length of the legs and in the measure of the angles. The pull of concentration is, in this case, very much increased. It is evident that the legs may vary arithmetically and the angles geometrically; or the angles arithmetically and the legs geometrically.

85. If, in the place of the straight lines, which form the legs, in any of the examples given, are substituted lines which in themselves induce movement, the feeling of Rhythm may be still further increased, provided the directions of movement are consistent.

In this case the movement is in the direction of increasing concentration and in the direction of the convergences.

If the movement of the convergences be contrary to the movement of concentration, there will be in the figure a contrary motion which may diminish or even entirely prevent the feeling of Rhythm. If the movement in one direction or the other predominates, we may still get the feeling of Rhythm, in spite of the drawback of the other and contrary movement.

In this case the linear convergences substituted for the straight lines are contrary to the direction of increasing concentration. The movement is doubtful.

86. Corresponding rhythms, set in contrary motion, give us the feeling of Balance rather than of Rhythm. The balance in such cases is a balance of movements.

This is an example of corresponding and opposed rhythms producing the feeling, not of Rhythm, but of Balance.

ATTITUDES

LINES IN DIFFERENT ATTITUDES

87. Any line or linear progression may be turned upon a center, and so made to take an indefinite number and variety of attitudes. It may be inverted upon an axis, and the inversion may be turned upon a center producing another series of attitudes which, except in the case of axial symmetry in the line, will be different from those of the first series.

In this case the line changes its attitude.

In this case I have inverted the line, and turning the inversion upon a center I get a different set of attitudes.

In this case, which is a case of axial symmetry in the line, the inversion gives us no additional attitudes.

THE ORDER OF HARMONY IN THE ATTITUDES OF LINES

88. When any line or linear progression is repeated, without change of attitude, we have a Harmony of Attitudes.

This is an illustration of Harmony of Attitudes. It is also an illustration of Interval-Harmony.

89. We have a Harmony of Attitudes, also, in the repetition of any relation of two or more attitudes, the relation of attitudes being repeated without change of attitude.

We have here a Harmony of Attitudes due to the repetition of a certain relation of attitudes, without change of attitude.

THE ORDER OF BALANCE IN THE ATTITUDES OF LINES

90. When a line or linear progression is inverted upon any axis or center, and we see the original line and its inversion side by side, we have a Balance of Attitudes.

The relation of attitudes I, II, of III, IV, and of I, II, III, IV, is that of Symmetrical Balance on a vertical axis. The relation of attitudes I, IV, and of II, III, is a relation of Balance but not of Symmetrical Balance. This is true, also, of the relation of I, III and of II, IV. Double inversions are never symmetrical, but they are illustrations of Balance. The balance of double inversions is central, not axial. These statements are all repetitions of statements previously made about positions.

THE ORDER OF RHYTHM IN THE ATTITUDES OF LINES

91. It often happens that a line repeated in different attitudes gives us the sense of movement. It does this when the grouping of the repetitions suggests instability. The movement is rhythmical when it exhibits a regularity of changes in the attitudes and in the intervals of the changes.

In this case we have a movement to the right, but no Rhythm, the intervals being irregular.

In this case the changes of attitude and the intervals of the changes being regular, the movement becomes rhythmical. The direction of the rhythm is clearly down-to-the-right.

92. In the repetition of any line we have a Harmony, due to the repetition. If the line is repeated in the same attitude, we have a Harmony of Attitudes. If it is repeated in the same intervals, we have a Harmony of Intervals. We have Harmony, also, in the repetition of any relation of attitudes or of intervals.

We have not yet considered the arrangement or composition of two or more lines of different measures and of different shapes.

THE COMPOSITION OF LINES

93. By the Composition of Lines I mean putting two or more lines together, in juxtaposition, in contact or interlacing. Our object in the composition of lines, so far as Pure Design is concerned, is to achieve Order, if possible Beauty, in the several modes of Harmony, Balance, and Rhythm.

HARMONY IN THE COMPOSITION OF LINES

94. We have Harmony in line-compositions when the lines which are put together correspond in all respects or in some respects, when they correspond in attitudes, and when there is a correspondence of distances or intervals.

In this case the lines of the composition correspond in tone, measure, and shape, but not in attitude; and there is no correspondence in distances or intervals.

In this case the attitudes correspond, as they did not in Fig. 120. There is still no correspondence of intervals.

Here we have the correspondence of intervals which we did not have either in Fig. 120 or in Fig. 121. There is not only a Harmony of Attitudes and of Intervals, in this case, but the Harmony of a repetition in one direction, Direction-Harmony. In all these cases we have the repetition of a certain angle, a right angle, and of a certain measure-relation between the legs of the angle, giving Measure and Shape-Harmony.

95. The repetition in any composition of a certain relation of measures, or of a certain proportion of measures, gives Measure-Harmony to the composition. The repetition of the relation one to three in the legs of the angle, in the illustrations just given, gives to the compositions the Harmony of a Recurring Ratio. By a proportion I mean an equality between ratios, when they are numerically different. The relation of one to three is a ratio. The relation of one to three and three to nine is a proportion. We may have in any composition the Harmony of a Repeated Ratio, as in Figs. 120, 121, 122, or we may have a Harmony of Proportions, as in the composition which follows.

96. To be in Harmony lines are not necessarily similar in all respects. As I have just shown, lines may be in Shape-Harmony, without being in any Measure-Harmony. Lines are approximately in harmony when they correspond in certain particulars, though they differ in others. The more points of resemblance between them, the greater the harmony. When they correspond in all respects we have, of course, a perfect harmony.

This is a case of Shape-Harmony without Measure-Harmony and without Harmony of Attitudes.

In this case we have a Harmony of Shapes and of Attitudes, without Measure-Harmony or Harmony of Intervals. This is a good illustration of a Harmony of Proportions.

Straight lines are in Harmony of Straightness because they are all straight, however much they differ in tone or measure. They are in Harmony of Measure when they have the same measure of length. The measures of width, also, may agree or disagree. In every agreement we have Harmony.

Angular lines are in Harmony when they have one or more angles in common. The recurrence of a certain angle in different parts of a composition brings Harmony into the composition. Designers are very apt to use different angles when there is no good reason for doing so, when the repetition of one would be more orderly.

The four lines in this composition have right angles in common. To that extent the lines are in Harmony. There is also a Harmony in the correspondence of tones and of width-measures in the lines. Considerable Harmony of Attitudes occurs in the form of parallelisms.

These two lines have simply one angle in common, a right angle, and the angle has the same attitude in both cases. They differ in other respects.

In these three lines the only element making for Harmony, except the same tone and the same width, is found in the presence in each line of a certain small arc of a circle. Straightness occurs in two of the lines but not in the third. There is a Harmony, therefore, between two of the lines from which the third is excluded. There is, also, a Harmony of Attitude in these two lines, in certain parallelisms.

BALANCE IN THE COMPOSITION OF LINES

97. Lines balance when in opposite attitudes. We get Balance in all inversions, whether single or double.

Here similar lines are drawn in opposite attitudes and we get Measure and Shape-Balance. In the above case the axis of balance is vertical. The balance is, therefore, symmetrical. Symmetrical Balance is obtained by the single inversion of any line or lines on a vertical axis. Double inversion gives a Balance of Measures and Shapes on a center. We have no Symmetry in double inversions. All this has been explained.

We have Measure and Shape-Balance on a center in this case. It is a case of double inversion. It is interesting to turn these double inversions on their centers, and to observe the very different effects they produce in different attitudes.

98. Shapes in order to balance satisfactorily must be drawn in the same measure, as in Fig. 131 which follows.

Here, in Fig. 132, we have Shape-Harmony without Measure-Harmony. It might be argued that we have in this case an illustration of Shape-Balance without Measure-Balance. Theoretically that is so, but Shape-Balance without Measure-Balance is never satisfactory. If we want the lines in Fig. 132 to balance we must find the balance-center between them, and then indicate that center by a symmetrical inclosure. We shall then have a Measure-Balance (occult) without Shape-Balance.

99. When measures correspond but shapes differ the balance-center may be suggested by a symmetrical inclosure or framing. When that is done the measures become balanced.

Here we have Measure-Harmony and a Measure-Balance without Shape-Harmony or Shape-Balance. The two lines have different shapes but the same measures, lengths and widths corresponding. The balance-center is found for each line. See pp. 54, 55. Between the two centers is found the center, upon which the two lines will balance. This center is then suggested by a symmetrical inclosure. The balancing measures in such cases may, of course, be turned upon their centers, and the axis connecting their centers may be turned in any direction or attitude, with no loss of equilibrium, so far as the measures are concerned.

The Balance of Measures here is just as good as it is in Fig. 133. The attitudes are changed but not the relation of the three balance-centers. The change of shape in the inclosure makes no difference.

100. Measure-Balance without Shape-Harmony or Shape-Balance is satisfactory only when the balance-center is unmistakably indicated or suggested, as in the examples which I have given.

101. There is another form of Balance which is to be inferred from what I have said, on page 18, of the Balance of Directions, but it needs to be particularly considered and more fully illustrated. I mean a Balance in which directions or inclinations to the right are counteracted by corresponding or equivalent directions or inclinations to the left. The idea in its simplest and most obvious form is illustrated in Fig. 22, on page 18. In that case the lines of inclination correspond. They do not necessarily correspond except in the extent of contrast, which may be distributed in various ways.

The balance of inclinations in this case is just as good as the balance in Fig. 22. There is no symmetry as in Fig. 22. Three lines balance against one. The three lines, however, show the same extent of contrast as the one. So far as the inclinations are concerned they will balance in any arrangement which lies well within the field of vision. The eye must be able to appreciate the fact that a disposition to fall to the right is counteracted by a corresponding or equivalent disposition to fall to the left.

This arrangement of the inclining lines is just as good as the arrangement in Fig. 135. The inclinations may be distributed in any way, provided they counteract one another properly.

In this case I have again changed the composition, and having suggested the balance-center of the lines, as attractions, by a symmetrical inclosure, I have added Measure-Balance (occult) to Inclination-Balance. The Order in Fig. 137 is greater than the Order in Figs. 135 and 136. In Fig. 137 two forms of Balance are illustrated, in the other cases only one. The value of any composition lies in the number of orderly connections which it shows.

In this case I have taken a long angular line and added a sufficient number and extent of opposite inclinations to make a balance of inclinations. The horizontal part of the long line is stable, so it needs no counteraction, but the other parts incline in various degrees, to the left or to the right. Each inclining part requires, therefore, either a corresponding line in a balancing direction, or two or more lines of equivalent extension in that direction. In one case I have set three lines to balance one, but they equal the one in length, that is to say, in the extent of contrast. We have in Fig. 138 an illustration of occult Measure-Balance and the Balance of Inclinations. I have illustrated the idea of Inclination-Balance by very simple examples. I have not considered the inclinations of curves, nor have I gone, at all, into the more difficult problem of balancing averages of inclination, when the average of two or more different inclinations of different extents of contrast has to be counteracted. In Tone-Relations the inclinations are of tone-contrasts, and a short inclination with a strong contrast may balance a long inclination with a slight one, or several inclinations of slight contrasts may serve to balance one of a strong contrast. The force of any inclining line may be increased by increasing the tone-contrast with the ground-tone. In tone-relations the problem becomes complicated and difficult. The whole subject of Inclination-Balance is one of great interest and worthy of a separate treatise.

RHYTHM IN THE COMPOSITION OF LINES

102. We will first consider the Measure-Rhythms which result from a gradual increase of scale, an increase in the extent of the contrasts. The intervals must, in such Rhythms, be regular and marked. They may be equal; they may alternate, or they may be regularly progressive.

In this case I feel that the direction of the Rhythm is up-to-the-right owing to the gradual increase of length and consequently of the extent of contrast in the lines, in that direction.

In this case I have, by means of regularly diminishing intervals, added the force of a crowding together of contrasting edges to the force of a gradual extension of them. The movement is still more strongly up-to-the-right.

In this case a greater extension of contrasts pulls one way and a greater crowding of contrasts the other. I think that crowding has the best of it. The movement, though much retarded, is, I feel, down-to-the-left rather than up-to-the-right, in spite of the fact that the greater facility of reading to the right is added to the force of extended contrasts.

103. Substituting unstable for stable attitudes in the examples just given, we are able to add the movement suggested by instability of attitude to the movement caused by a gradual extension of contrasts.

The movement up-to-the-right in Fig. 139 is here connected with an inclination of all the lines down-to-the-right.

Here the falling of the lines down-to-the-left counteracts the movement in the opposite direction which is caused by the extension of contrasting edges in that direction. A crowding together of the lines, due to the diminution of intervals toward the left, adds force to the movement in that direction.

In this case a movement up is caused by convergences, a movement down by crowding. The convergences are all up, the crowding down. I think that the convergences have it. I think the movement is, on the whole, up. The intervals of the crowding down diminish arithmetically.

The convergences and the crowding of attractions are, here, both up-to-the-right. The Rhythm is much stronger than it was in Fig. 144. The intervals are those of an arithmetical progression.

The movement here is up-to-the-right, because of convergences in that direction and an extension of contrasts in that direction.

In this case the two movements part company. One leads the eye up-to-the-left, the other leads it up-to-the-right. The movement as a whole is approximately up. As the direction of the intervals is horizontal, not vertical, this is a case of movement without Rhythm. The movement will become rhythmic only in a vertical repetition. That is to say, the direction or directions of the movement in any Rhythm and the direction or directions of its repetitions must coincide. In Fig. 139, the movement is up-to-the-right, and the intervals may be taken in the same direction, but in Fig. 147 the movement is up. The intervals cannot be taken in that direction. It is, therefore, impossible to get any feeling of Rhythm from the composition. We shall get the feeling of Rhythm only when we repeat the movement in the direction of the movement, which is up.

Here we have a vertical repetition of the composition given in Fig. 147. The result is an upward movement in regular and marked intervals, answering to our understanding of Rhythm.

In this case we have a curved movement. The lines being spaced at regular intervals, the movement is in regular and marked measures. Its direction is due to an increase in the number of attractions, to crowding, and to convergences. The movement is, accordingly, rhythmical.

The movement of Fig. 149 is here partly destroyed by an inversion and opposition of attitudes and directions. The movement is, on the whole, up, but it can hardly be described as rhythmical, because it has no repetition upwards, as it has in the next illustration, Fig. 151. Before proceeding, however, to the consideration of Fig. 151, I want to call the attention of the reader to the fact that we have in Fig. 150 a type of Balance to which I have not particularly referred. It is a case of unsymmetrical balance on a vertical axis. The balancing shapes and movements correspond. They incline in opposite directions. They diverge equally from the vertical axis. The inclinations balance. At the same time the composition does not answer to our understanding of Symmetry. It is not a case of right and left balance on the vertical axis. The shapes and movements are not right and left and opposite. One of the shapes is set higher than the other. The balance is on the vertical. It is obvious, but it is not symmetrical. It is a form of Balance which has many and very interesting possibilities.

The repetition, in this case, of somewhat contrary movements, a repetition at equal intervals on a vertical axis, gives us more Balance than Rhythm. We feel, however, a general upward movement through the repetitions and, as this movement is regular, it must be described as rhythmical.

The feeling of upward movement in Fig. 151 is, no doubt, partly due to the suggestion of upward growth in certain forms of vegetation. The suggestion is inevitable. So far as the movement is caused by this association of ideas it is a matter, not of sensation, but of perception. The consideration of such associations of ideas does not belong, properly, to Pure Design, where we are dealing with sense-impressions, exclusively.

104. Rhythm is not inconsistent with Balance. It is only necessary to get movements which have the same or nearly the same direction and which are rhythmical in character to balance on the same axis and we have a reconciliation of the two principles.

Here we have a Rhythm, of somewhat contrary movements, with Balance,—Balance on a diagonal axis. The Balance is not satisfactory. The Balance of Inclinations is felt more than the Balance of Shapes.

In this case we have the combination of a Rhythm of somewhat contrary, but on the whole upward, movements with Symmetry.

If the diverging movements of Fig. 153 should be made still more diverging, so that they become approximately contrary and opposite, the feeling of a general upward movement will disappear. The three movements to the right will balance the three movements to the left, and we shall have an illustration of Symmetrical Balance, with no Rhythm in the composition as a whole. It is doubtful whether the balance of contrary and opposite movements is satisfactory. Our eyes are drawn in opposite directions, away from the axis of balance, instead of being drawn toward it. Our appreciation of the balance must, therefore, be diminished. Contrary and opposite movements neutralize one another, so we have neither rest nor movement in the balance of contrary motions.

By bringing the divergences of movement together, gradually, we shall be able to increase, considerably, the upward movement shown in Fig. 153. At the same time, the suggestion of an upward growth of vegetation becomes stronger. The increase of movement will be partly explained by this association of ideas.

Here all the movements are pulled together into one direction. The Rhythm is easier and more rapid. The Balance is just as good. The movement in this case is no doubt facilitated by the suggestion of upward growth. It is impossible to estimate the force which is added by such suggestions and associations.

Here the movements come together in another way.

The number and variety of these illustrations might, of course, be indefinitely increased. Those which I have given will, I think, serve to define the principal modes of line-composition, when the lines are such as we choose to draw.

THE COMPOSITION OF VARIOUS LINES

105. In most of the examples I have given I have used repetitions of the same line or similar lines. When the lines which are put together are not in harmony, when they are drawn, as they may be, without any regard to the exigencies of orderly composition, the problem becomes one of doing the best we can with our terms. We try for the greatest possible number of orderly connections, connections making for Harmony, Balance, and Rhythm. We arrange the lines, so far as possible, in the same directions, giving them similar attitudes, getting, in details, as much Harmony of Direction and of Attitudes as possible, and establishing as much Harmony of Intervals as possible between the lines. By spacing and placing we try to get differences of character as far as possible into regular alternations or gradations in which there will be a suggestion either of Harmony or of Rhythm. A suggestion of Symmetry is sometimes possible. Occult Balance is possible in all cases, as it depends, not upon the terms balanced, but upon the indication of a center of attractions by a symmetrical framing of them.

Let us take seven lines, with a variety of shape-character, with as little Shape-Harmony as possible, and let us try to put these lines together in an orderly way.

With these lines, which show little or no harmony of character, which agree only in tone and in width-measure, lines which would not be selected certainly as suitable material for orderly compositions, I will make three compositions, getting as much Order into each one as I can, just to illustrate what I mean. I shall not be able to achieve a great deal of Order, but enough, probably, to satisfy the reader that the effort has been worth while.

In this case I have achieved the suggestion of a Symmetrical Balance on a vertical axis with some Harmony of Directions and of Attitudes and some Interval-Harmony.

In this case, also, I have achieved a suggestion of Order, if not Order itself. Consider the comparative disorder in Fig. 156, where no arrangement has been attempted.

Here is another arrangement of the same terms. Fortunately, in all of these cases, the lines agree in tone and in width-measure. That means considerable order to begin with.

This problem of taking any terms and making the best possible arrangement of them is a most interesting problem, and the ability to solve it has a practical value. We have the problem to solve in every-day life; when we have to arrange, as well as we can, in the best possible order, all the useful and indispensable articles we have in our houses. To achieve a consistency and unity of effect with a great number and variety of objects is never easy. It is often very difficult. It is particularly difficult when we have no two objects alike, no correspondence, no likeness, to make Harmony. With the possibility of repetitions and inversions the problem becomes comparatively easy. With repetitions and inversions we have the possibility, not only of Harmony, but of Balance and Rhythm. With inversions we have the possibility, not only of Balance, but of Symmetrical Balance, and when we have that we are not at all likely to think whether the terms of which the symmetry is composed are in harmony or not. We feel the Order of Symmetry and we are satisfied.

In this design I repeat an inversion of the arrangement in Fig. 158. The result is a symmetry, and no one is likely to ask whether the elements of which it is composed are harmonious or not. By inversions, single and double, it is possible to achieve the Order of Balance, in all cases.

For this design I have made another arrangement of my seven lines. The arrangement suggests movement. In repeating the arrangement at regular and equal intervals, without change of attitude, I produce the effect of Rhythm. Without resorting to inversion, it is difficult to make even an approximation to Symmetry with such terms (see Fig. 157), but there is little or no difficulty in making a consistent or fairly consistent movement out of them, which, being repeated at regular intervals, without change of attitude, or with a gradual change of attitude, will produce the effect of Rhythm.

Up to this point I have spoken of the composition of lines in juxtaposition, that is to say, the lines have been placed near together so as to be seen together. I have not spoken of the possibilities of Contact and Interlacing. The lines in any composition may touch one another or cross one another. The result will be a composition of connected lines. In certain cases the lines will become the outlines of areas. I will defer the illustration of contacts and interlacings until I come to consider the composition of outlines.

OUTLINES

DEFINITION OF OUTLINES

106. Outlines are lines which, returning to themselves, make inclosures and describe areas of different measures and shapes. What has been said of lines may be said, also, of outlines. It will be worth while, however, to give a separate consideration to outlines, as a particularly interesting and important class of lines.

As in the case of dots and lines, I shall disregard the fact that the outlines may be drawn in different tones, making different contrasts of value, color, or color-intensity with the ground-tone upon which they are drawn. I shall, also, disregard possible differences of width in the lines which make the outlines. I shall confine my attention, here, to the measures and shapes of the outlines and to the possibilities of Harmony, Balance, and Rhythm in those measures and shapes.

HARMONY, BALANCE, AND RHYTHM IN OUTLINES

107. What is Harmony or Balance or Rhythm in a line is Harmony, Balance, or Rhythm in an Outline.

In this outline we have Measure-Harmony in the angles, Measure-Harmony of lengths in the legs of the angles, Measure and Shape-Balance on a center and Symmetry on the vertical axis. The same statement will be true of all polygons which are both equiangular and equilateral, when they are balanced on a vertical axis.

In this case we have Measure-Harmony of angles but no Measure-Harmony of lengths in the legs of the angles. We have lost Measure and Shape-Balance on a center which we had in the previous example.

In this case the angles are not all in a Harmony of Measure; but we have Measure-Harmony of lengths in the legs of the angles, and we have Measure and Shape-Balance on a center. There is a certain Harmony in the repetition of a relation of two angles.

In this case we have Measure-Harmony in the angles, which are equal, and a Harmony due to the repetition of a certain measure-relation in the legs of the angles. As in Fig. 162, we have here a Measure and Shape-Balance on a center and Symmetry on the vertical axis. This polygon is not equilateral, but its sides are symmetrically disposed. Many interesting and beautiful figures may be drawn in these terms.

We have in the circle the most harmonious of all outlines. The Harmony of the circle is due to the fact that all sections of it have the same radius and equal sections of it have, also, the same angle-measure. The circle is, of course, a perfect illustration of Measure and Shape-Balance on a center. The balance is also symmetrical. We have a Harmony of Directions in the repetition of the same change of direction at every point of the outline, and we have a Harmony of Distances in the fact that all points of the outline are equally distant from the balance-center, which is unmistakably felt.

The Ellipse is another example of Measure and Shape-Balance on a center. In this attitude it is also an illustration of Symmetry.

In this case we still have balance but no symmetry. The attitude suggests movement. We cannot help feeling that the figure is falling down to the left. A repetition at equal intervals would give us Rhythm.

In this case we have an outline produced by the single inversion of a line in which there is the repetition of a certain motive in a gradation of measures. That gives Shape-Harmony without Measure-Harmony. This is a case of Symmetrical Balance. It is also a case of rhythmic movement upward. The movement is mainly due to convergences.

In this case, also, the shapes repeated on the right side and on the left side of the outline show movements which become in repetitions almost rhythmical. The movement is up in spite of the fact that each part of the movement is, in its ending, down. We have in these examples symmetrical balance on a vertical axis combined with rhythm on the same axis. It may be desirable to find the balance-center of an outline when only the axis is indicated by the character of the outline. The principle which we follow is the one already described. In Fig. 169 we have a symmetrical balance on a vertical axis, but there is nothing to indicate the balance-center. It lies on the axis somewhere, but there is nothing to show us where it is. Regarding the outline as a line of attractions, the eye is presumably held at their balance-center, wherever it is. Exactly where it is is a matter of visual feeling. The balance-center being ascertained, it may be indicated by a symmetrical outline or inclosure, the center of which cannot be doubtful.

The balance-center, as determined by visual feeling, is here clearly indicated. In this case besides the balance on a center we have also the Symmetry which we had in Fig. 169.

The sense of Balance is, in this case, much diminished by the change of attitude in the balanced outline. We have our balance upon a center, all the same; but the balance on the vertical axis being lost, we have no longer any Symmetry. It will be observed that balance on a center is not inconsistent with movement. If this figure were repeated at equal intervals without change of attitude, or with a gradual change, we should have the Rhythm of a repeated movement.

In some outlines only certain parts of the outlines are orderly, while other parts are disorderly.

In the above outline we have two sections corresponding in measure and shape-character and in attitude. We have, therefore, certain elements of the outline in harmony. We feel movement but not rhythm in the relation of the two curves. There is no balance of any kind.

We ought to be able to recognize elements of order as they occur in any outline, even when the outline, as a whole, is disorderly.

In order to balance the somewhat irregular outline given in Fig. 173, we follow the procedure already described. The effect, however, is unsatisfactory. The composition lacks stability.

The attitude of the figure is here made to conform, as far as possible, to the shape and attitude of the symmetrical framing: this for the sake of Shape and Attitude-Harmony. The change of attitude gives greater stability.

INTERIOR DIMENSIONS OF AN OUTLINE

108. A distinction must be drawn between the measures of the outline, as an outline, and the measures of the space or area lying within the outline: what may be called the interior dimensions of the outline.

In this case we must distinguish between the measures of the outline and the dimensions of the space inclosed within it. When we consider the measures—not of the outline, but of the space or area inside of the outline—we may look in these measures, also, for Harmony, for Balance, or for Rhythm, and for combinations of these principles.

HARMONY IN THE INTERIOR DIMENSIONS OF AN OUTLINE

109. We have Harmony in the interior dimensions of an outline when the dimensions correspond or when a certain relation of dimensions is repeated.

In this case we have an outline which shows a Harmony in the correspondence of two dimensions.

In this case we have Harmony in the correspondence of all vertical dimensions, Harmony in the correspondence of all horizontal dimensions, but no relation of Harmony between the two. It might be argued, from the fact that the interval in one direction is twice that in the other, that the dimensions have something in common, namely, a common divisor. It is very doubtful, however, whether this fact is appreciable in the sense of vision. The recurrence of any relation of two dimensions would, no doubt, be appreciated. We should have, in that case, Shape-Harmony.

In this circle we have a Measure-Harmony of diameters.

In this case we have a Harmony due to the repetition of a certain ratio of vertical intervals: 1:3, 1:3, 1:3.

110. Any gradual diminution of the interval between opposite sides in an outline gives us a convergence in which the eye moves more or less rapidly toward an actual or possible contact. The more rapid the convergence the more rapid the movement.

In this case we have not only symmetrical balance on a vertical axis but movement, in the upward and rapid convergence of the sides BA and CA toward the angle A. The question may be raised whether the movement, in this case, is up from the side BC to the angle A or down from the angle A toward the side BC. I think that the reader will agree that the movement is from the side BC into the angle A. In this direction the eye is more definitely guided. The opposite movement from A toward BC is a movement in diverging directions which the eye cannot follow to any distance. As the distance from BC toward A decreases, the convergence of the sides BA and CA is more and more helpful to the eye and produces the feeling of movement. The eye finds itself in a smaller and smaller space, with a more and more definite impulse toward A. It is a question whether the movement from BC toward A is rhythmical or not. The movement is not connected with any marked regularity of measures. I am inclined to think, however, that the gradual and even change of measures produces the feeling of equal changes in equal measures. If so, the movement is rhythmical.

When the movement of the eye in any convergence is a movement in regular and marked measures, as in the example which follows, the movement is rhythmical, without doubt.

The upward movement in this outline, being regulated by measures which are marked and equal, the movement is certainly rhythmical, according to our understanding and definition of Rhythm. Comparing Fig. 181 with Fig. 182, the question arises, whether the movement in Fig. 182 is felt to be any more rhythmical than the movement in Fig. 181. The measures of the movement in Fig 181 are not marked, but I cannot persuade myself that they are not felt in the evenness of the gradation. The movement in Fig. 181 is easier than it is in Fig. 182, when the marking of the measures interferes with the movement.

In this case we have another illustration like Fig. 182, only the measures of the rhythm are differently marked. The force of the convergence is greatest in Fig. 181. It is somewhat diminished by the measure-marks in Fig. 182. It is still further diminished, in Fig. 183, by the angles that break the measures.

In this case the movement is more rapid again, the measures being measures of an arithmetical progression. There is a crowding together of attractions in the direction of the convergence, and the movement is easier than it is in Fig. 183, in spite of the fact that the lines of convergence are more broken in Fig. 184. There is an arithmetical diminution of horizontal as well as of vertical lines in Fig. 184.

In this case the measures of the rhythm are in the terms of a geometrical progression. The crowding together of attractions is still more rapid in this case and the distance to be traversed by the eye is shorter. The convergence, however, is less compelling, the lines of the convergence being so much broken—unnecessarily.
