IX.—TWO VALUES—VARIATIONS—DESIGN
Dark-and-light has not been considered in school curricula, except in its limited application to representation. The study of “light and shade” has for its aim, not the creation of a beautiful idea in terms of contrasting masses of light and dark, but merely the accurate rendering of certain facts of nature,—hence is a scientific rather than an artistic exercise. The pupil who begins in this way will be embarrassed in advanced work by lack of experience in arranging and differentiating tones. Worse than that, it tends to cut him off from the appreciation of one whole class of great works of art. As in the case of Line, so again in this is manifest the narrowness and weakness of the scheme of nature-imitating as a foundation for art education. The Realistic standard always tends to the decay of art. The student in an academic school, feeling the necessity for a knowledge of Dark-and-Light when he begins to make original compositions, has usually but one resource, that of sketching the “spotting” as he calls it, of good designs and pictures—an excellent practice if followed intelligently. His difficulties may be overcome (1) by seeing that Notan is an element distinct from Line or Color; (2) by attempting its mastery in progressive stages leading to appreciation.
METHOD OF STUDY.
Line melts into Tone through the clustering of many lines. Direct study of tone-intervals begins with composition in two values—the simplest form of Notan. There may be several starting-points; one might begin by blotting ink or charcoal upon paper, by copying the darks and lights from photographs of masterpieces, or by making scales. Experience has shown that the straight-line design and the flat black ink wash are most satisfactory for earlier exercises in two values. Instead of black and white, or black and gray, one might use two grays of different values, or two values of one color (say light blue and dark blue) according to need. The aim being to understand Notan as something by which harmony may be created, it is best to avoid Representation at first. Notan must not be confounded with Light and Shade, Modelling or anything that refers to imitation of natural objects.
The beginner may imagine that not much can be done with flat black against flat white, but let him examine the decorative design of the world. He will find the black and white check and patterns derived from it, in old velvets of Japan, in the woven and printed textiles of all nations, in marble floors, inlaid boxes and architectural [pg 60]
[pg 61] ornament. The use of these two simple tones is as universal as Art itself. They appear in the black vine on the white marble floor of the Church of the Miracoli at Venice; on the wall of the Arabian Mosque, and the frieze of the Chinese temple. They have come into favor on book covers and page borders. Aubrey Beardsley went scarcely beyond them. R. Anning Bell and other artists have boldly carried them into pictorial work in the illustration of children's books.
