Mme. LeBrun and Her Daughter, a painting by Mme. Vigée-Lebrun. A good figure composition on the basis of a triangle. Compare with the “still” shown facing [page 61]. See also pages [62] and [76].
Rhythm in music may be partially described as a peculiar alternating movement, with an alternation between sounds of different pitch, quality, and quantity; between different sound groups, and between sound and silence. The rhythm of visible motion is of a somewhat similar nature, as we shall see in Chapter VIII. But a sense of alternating movement may be produced by things which are not themselves in motion. We can, therefore, find rhythm in fixed lines, shapes, tones, colors, and textures. This we shall call rhythm of fixed design.
The peculiar thing about the element of alternation in rhythm which distinguishes it from mere repetition, is that it is not regular, like the swinging of a pendulum, but contains numerous variations from regularity. But, while the symmetry of rhythm is only partial, so also the variety is limited. It is the combined effect of these two factors which makes rhythm delightful. Repetition or symmetry in a line or a pattern is pleasurable because, as explained in Chapter III, it enables us to see much with ease. But, at the same time, subtle or even bold variations are appealing because they relieve us of monotony, stimulate our interest, and lead our eyes in search of further variations.
A familiar rhythm of line is that of the reverse curve, which Hogarth called “the line of beauty.” This line is beautifully used in the painting “Daylight and Lamplight,” facing [page 39]. Observe the effect of alternation with variety in the lines which bound the urn, the woman’s figure, and the various shadows and lights in the background. Your eye sweeps over those paths without effort, and you get a sense of movement, as though you yourself were drawing these lines with a brush or crayon. Analyze the composition and you will see how richly the lines are woven together. Compare all the small curves with each other, compare all the larger curves, all the short straight lines, all the longer straight lines, etc., and you will discover an amazing amount of alternation and repetition, with an equally amazing amount of deviation from regularity.
Imagine that the painting which we have just analyzed is an accented moment in a motion picture, and you must imagine another similar design a few seconds earlier in the action and still another one a few seconds later, as the woman walks gracefully through the room. In fact, there would be a whole series of similar designs during the brief time that the woman’s figure and the urn are in decorative contact. The instant of action which the painter has chosen to fix on canvas might well be the same instant which you would select as the pictorial climax in this motion picture. This climax, accented perhaps with a pause, accented also by the pictorial approach and departure, is something which you would long remember as a rhythmical moment in the photoplay.
In the picture which we have just described the rhythm is found chiefly in the continuity and richness of line and in a certain active balancing of similar with dissimilar lines. The design is simple, almost plain. It is a single pattern which does not recur again within the frame. Quite different in type is the composition of a group picture such as “The Banquet of the Officers of St. Andrew,” facing [page 79], where the rhythm is in the flow of patterns rather than in the flow of lines. Take a hat, for example, as the decorative theme and observe how definitely, yet how subtly, that theme is four times varied. Note further how the curves of the hats are echoed, always with variety, in the ruffs.
From Polly of the Circus. Compare this “still” with Banquet of the Officers of St. Andrew (below) and you get at once the distinct impression that the painting depicts a larger crowd than the “still.” As a matter of fact, the painter has used only twelve men to produce his effect, while the motion picture director has employed seventeen men, a woman, and a horse. This difference illustrates the practical utility of pictorial design. See [page 57].
