The Practice and Science of Drawing

#This quality of tone music is most dominant when the masses are large and simple#, when the contemplation of them is not disturbed by much variety, and they have little variation of texture and gradation. A slight mist will often improve the tone of a landscape for this reason. It simplifies the tones, masses them together, obliterating many smaller varieties. I have even heard of the tone of a picture being improved by such a mist scrambled or glazed over it. [Illustration: Plate XLIII. MONTE SOLARO CAPRI Study on brown paper in charcoal and white chalk.] The powder on a lady's face, when not over-done, is an improvement for the same reason. It simplifies the tones by destroying the distressing shining lights that were cutting up the masses; and it also destroys a large amount of half tone, broadening the lights almost up to the commencement of the shadows. #Tone relationships are most sympathetic when the middle values of your scale only are used, that is to say, when the lights are low in tone and the darks high.# #They are most dramatic and intense when the contrasts are great and the jumps from dark to light sudden.# The sympathetic charm of half-light effects is due largely to the tones being of this middle range only; whereas the striking dramatic effect of a storm clearing, in which you may get a landscape brilliantly lit by the sudden appearance of the sun, seen against the dark clouds of the retreating storm, owes much of its dramatic quality to contrast. The strong contrasts of tone values coupled with the strong colour contrast between the warm sunlit land and the cold angry blue of the storm, gives such a scene much dramatic effect and power. The subject of values will be further treated in dealing with unity of tone. [Sidenote: Variety in Quality and Texture] Variety in quality and nature is almost too subtle to write about with any prospect of being understood. The play of different qualities and textures in the masses that go to form a picture must be appreciated at first hand, and little can be written about it. Oil paint is capable of almost unlimited variety in this way. But it is better to leave the study of such qualities until you have mastered the medium in its more simple aspects. The particular tone music of which we were speaking is not helped by any great use of this variety. A oneness of quality throughout the work is best suited to exhibit it. Masters of tone, like Whistler, preserve this oneness of quality very carefully in their work, relying chiefly on the grain of a rough canvas to give the necessary variety and prevent a deadness in the quality of the tones. But when more force and brilliancy are wanted, some use of your paint in a crumbling, broken manner is necessary, as it catches more light, thus increasing the force of the impression. Claude Monet and his followers in their search for brilliancy used this quality throughout many of their paintings, with new and striking results. But it is at the sacrifice of many beautiful qualities of form, as this roughness of surface does not lend itself readily to any finesse of modelling. In the case of Claude Monet's work, however, this does not matter, as form with all its subtleties is not a thing he made any attempt at exploiting. Nature is sufficiently vast for beautiful work to be done in separate departments of vision, although one cannot place such work on the same plane with successful pictures of wider scope. And the particular visual beauty of sparkling light and atmosphere, of which he was one of the first to make a separate study, could hardly exist in a work that aimed also at the significance of beautiful form, the appeal of form, as was explained in an earlier chapter, not being entirely due to a visual but to a mental perception, into which the sense of touch enters by association. The scintillation and glitter of light destroys this touch idea, which is better preserved in quieter lightings. There is another point in connection with the use of thick paint, that I don't think is sufficiently well known, and that is, its greater readiness to be discoloured by the oil in its composition coming to the surface. Fifteen years ago I did what it would be advisable for every student to do as soon as possible, namely, make a chart of the colours he is likely to use. Get a good white canvas, and set upon it in columns the different colours, very much as you would do on your palette, writing the names in ink beside them. Then take a palette-knife, an ivory one by preference, and drag it from the individual masses of paint so as to get a gradation of different thicknesses, from the thinnest possible layer where your knife ends to the thick mass where it was squeezed out of the tube. It is also advisable to have previously ruled some pencil lines with a hard point down the canvas in such a manner that the strips of paint will cross the lines. This chart will be of the greatest value to you in noting the effect of time on paint. To make it more complete, the colours of several makers should be put down, and at any rate the whites of several different makes should be on it. As white enters so largely into your painting it is highly necessary to use one that does not change. The two things that I have noticed are that the thin ends of the strips of white have invariably kept whiter than the thick end, and that all the paints have become a little more transparent with time. The pencil lines here come in useful, as they can be seen through the thinner portion, and show to what extent this transparency has occurred. But the point I wish to emphasise is that at the thick end the larger body of oil in the paint, which always comes to the surface as it dries, has darkened and yellowed the surface greatly; while the small amount of oil at the thin end has not darkened it to any extent. Claude Monet evidently knew this, and got over the difficulty by painting on an absorbent canvas, which sucks the surplus oil out from below and thus prevents its coming to the surface and discolouring the work in time. When this thick manner of painting is adopted, an absorbent canvas should always be used. It also has the advantage of giving a dull dry surface of more brilliancy than a shiny one. Although not so much as with painting, varieties of texture enter into drawings done with any of the mediums that lend themselves to mass drawing; charcoal, conté crayon, lithographic chalk, and even red chalk and lead pencil are capable of giving a variety of textures, governed largely by the surface of the paper used. But this is more the province of painting than of drawing proper, and charcoal, which is more painting than drawing, is the only medium in which it can be used with much effect. [Sidenote: Variety of Edges.] There is a very beautiful rhythmic quality in the play from softness to sharpness on the edges of masses. A monotonous sharpness of edge is hard, stern, and unsympathetic. This is a useful quality at times, particularly in decorative work, where the more intimate sympathetic qualities are not so much wanted, and where the harder forms go better with the architectural surroundings of which your painted decoration should form a part. On the other hand, a monotonous softness of edge is very weak and feeble-looking, and too entirely lacking in power to be desirable. If you find any successful work done with this quality of edge unrelieved by any sharpnesses, it will depend on colour, and not form, for any qualities it may possess. Some amount of softness makes for charm, and is extremely popular: "#I do# like that because it's so nice and soft" is a regular show-day remark in the studio, and is always meant as a great compliment, but is seldom taken as such by the suffering painter. But a balance of these two qualities playing about your contours produces the most delightful results, and the artist is always on the look out for such variations. He seldom lets a sharpness of edge run far without losing it occasionally. It may be necessary for the hang of the composition that some leading edges should be much insisted on. But even here a monotonous sharpness is too dead a thing, and although a firmness of run will be allowed to be felt, subtle variations will be introduced to prevent deadness. The Venetians from Giorgione's time were great masters of this music of edges. The structure of lines surrounding the masses on which their compositions are built were fused in the most mysterious and delightful way. But although melting into the surrounding mass, they are always firm and never soft and feeble. Study the edge in such a good example of the Venetian manner as the "Bacchus and Ariadne" at the National Gallery, and note where they are hard and where lost. There is one rather remarkable fact to be observed in this picture and many Venetian works, and this is that the #most accented edges are reserved for unessential parts#, like the piece of white drapery on the lower arm of the girl with the cymbals, and the little white flower on the boy's head in front. The edges on the flesh are everywhere fused and soft, the draperies being much sharper. You may notice the same thing in many pictures of the later Venetian schools. The greatest accents on the edges are rarely in the head, except it may be occasionally in the eyes. But they love to get some strongly-accented feature, such as a crisply-painted shirt coming against the soft modelling of the neck, to balance the fused edges in the flesh. In the head of Philip IV in our National Gallery the only place where Velazquez has allowed himself anything like a sharp edge is in the high lights on the chain hanging round the neck. The softer edges of the principal features in these compositions lend a largeness and mystery to these parts, and to restore the balance, sharpnesses are introduced in non-essential accessories. In the figure with the white tunic from Velazquez's "Surrender of Breda," here reproduced, note the wonderful variety on the edges of the white masses of the coat and the horse's nose, and also that the sharpest accents are reserved for such non-essentials as the bows on the tunic and the loose hair on the horse's forehead. Velazquez's edges are wonderful, and cannot be too carefully studied. He worked largely in flat tones or planes; but this richness and variety of his edges keeps his work from looking flat and dull, like that of some of his followers. I am sorry to say this variety does not come out so well in the reproduction on page 194 [Transcribers Note: Plate XLIV] as I could have wished, the half-tone process having a tendency to sharpen edges rather monotonously. This quality is everywhere to be found in nature. If you regard any scene pictorially, looking at it as a whole and not letting your eye focus on individual objects wandering from one to another while being but dimly conscious of the whole, but regarding it as a beautiful ensemble; you will find that the boundaries of the masses are not hard continuous edges but play continually along their course, here melting imperceptibly into the surrounding mass, and there accentuated more sharply. Even a long continuous line, like the horizon at sea, has some amount of this play, which you should always be on the look out for. But when the parts only of nature are regarded and each is separately focussed, hard edges will be found to exist almost everywhere, unless there is a positive mist enveloping the objects. And this is the usual way of looking at things. But a picture that is a catalogue of many little parts separately focussed will not hang together as one visual impression. [Illustration: Plate XLIV. PART OF THE SURRENDER OF BREDA. BY VELAZQUEZ Note the varied quantity of the edge in white mass of tunic. (The reproduction does not unfortunately show this as well as the original.) _Photo Anderson_] In naturalistic work the necessity for painting to one focal impression is as great as the necessity of painting in true perspective. What perspective has done for drawing, the impressionist system of painting to one all-embracing focus has done for tone. Before perspective was introduced, each individual object in a picture was drawn with a separate centre of vision fixed on each object in turn. What perspective did was to insist that all objects in a picture should be drawn in relation to one fixed centre of vision. And whereas formerly each object was painted to a hard focus, whether it was in the foreground or the distance, impressionism teaches that you cannot have the focus in a picture at the same time on the foreground and the distance. Of course there are many manners of painting with more primitive conventions in which the consideration of focus does not enter. But in all painting that aims at reproducing the impressions directly produced in us by natural appearances, this question of focus and its influence on the quality of your edges is of great importance. Something should be said about the serrated edges of masses, like those of trees seen against the sky. These are very difficult to treat, and almost every landscape painter has a different formula. The hard, fussy, cut-out, photographic appearance of trees misses all their beauty and sublimity. There are three principal types of treatment that may serve as examples. In the first place there are the trees of the early Italian painters, three examples of which are illustrated on page 197 [Transcribers Note: Diagram XXIII]. A thin tree is always selected, and a rhythmic pattern of leaves against the sky painted. This treatment of a dark pattern on a light ground is very useful as a contrast to the softer tones of flesh. But the treatment is more often applied nowadays to a spray of foliage in the foreground, the pattern of which gives a very rich effect. The poplar trees in Millais' "Vale of Rest" are painted in much the same manner as that employed by the Italians, and are exceptional among modern tree paintings, the trees being treated as a pattern of leaves against the sky. Millais has also got a raised quality of paint in his darks very similar to that of Bellini and many early painters. Giorgione added another tree to landscape art: the rich, full, solidly-massed forms that occur in his "Concert Champêtre" of the Louvre, reproduced on page 151 [Transcribers Note: Plate XXXIII]. In this picture you may see both types of treatment. There are the patterns of leaves variety on the left and the solidly-massed treatment on the right. [Illustration: Diagram XXIII. EXAMPLES OF EARLY ITALIAN TREATMENT OF TREES A. From pictures in Oratorio di S. Ansano. "Il trionfo dell' Amore," attributed to Botticelli. B. From "L'Annunziazione," by Botticelli, Uffizi, Florence. C. From "La Vergine," by Giovanni Bellini in the Accademia, Venice.] Corot in his later work developed a treatment that has been largely followed since. Looking at trees with a very wide focus, he ignored individual leaves, and resolved them into masses of tone, here lost and here found more sharply against the sky. The subordinate masses of foliage within these main boundaries are treated in the same way, resolved into masses of infinitely varying edges. This play, this lost-and-foundness at his edges is one of the great distinguishing charms of Corot's trees. When they have been painted from this mass point of view, a suggestion of a few leaves here and a bough there may be indicated, coming sharply against the sky, but you will find this basis of tone music, this crescendo and diminuendo throughout all his later work (see illustration, page 215 [Transcribers Note: Diagram XXVI]). These are three of the more extreme types of trees to be met with in art, but the variations on these types are very numerous. Whatever treatment you adopt, the tree must be considered as a whole, and some rhythmic form related to this large impression selected. And this applies to all forms with serrated edges: some large order must be found to which the fussiness of the edges must conform. The subject of edges generally is a very important one, and one much more worried over by a master than by the average student. It is interesting to note how all the great painters have begun with a hard manner, with edges of little variety, from which they have gradually developed a looser manner, learning to master the difficulties of design that hard contours insist on your facing, and only when this is thoroughly mastered letting themselves develop freely this play on the edges, this looser handling.
