With Gauguin the case is different. The generation of his disciples which followed him—I put it thus to distinguish them from his actual pupils at Pont Aven, Serusier and the rest—carried the tendency further. One hesitates to mention Derain, for his beginnings, full of vitality and promise, have given place to a dreary compromise with Cubism, without visible future, and above all without humour. But there is no better example of the development of synthetic symbolism than his first book of woodcuts.

[Footnote: L'Enchanteur pourrissant, par Guillaume Apollinaire, avec illustrations gravees sur bois par Andre Derain. Paris, Kahnweiler, 1910.]

Here is work which keeps the merest semblance of conventional form, which gives its effect by startling masses of black and white, by sudden curves, but more frequently by sudden angles.

[Footnote: The renaissance of the angle in art is an interesting feature of the new movement. Not since Egyptian times has it been used with such noble effect. There is a painting of Gauguin's at Hagen, of a row of Tahitian women seated on a bench, that consists entirely of a telling design in Egyptian angles. Cubism is the result of this discovery of the angle, blended with the influence of Cezanne.]

In the process of the gradual abandonment of natural form the "angle" school is paralleled by the "curve" school, which also descends wholly from Gauguin. The best known representative is Maurice Denis. But he has become a slave to sentimentality, and has been left behind. Matisse is the most prominent French artist who has followed Gauguin with curves. In Germany a group of young men, who form the Neue Kunstlevereinigung in Munich, work almost entirely in sweeping curves, and have reduced natural objects purely to flowing, decorative units.

But while they have followed Gauguin's lead in abandoning representation both of these two groups of advance are lacking in spiritual meaning. Their aim becomes more and more decorative, with an undercurrent of suggestion of simplified form. Anyone who has studied Gauguin will be aware of the intense spiritual value of his work. The man is a preacher and a psychologist, universal by his very unorthodoxy, fundamental because he goes deeper than civilization. In his disciples this great element is wanting. Kandinsky has supplied the need. He is not only on the track of an art more purely spiritual than was conceived even by Gauguin, but he has achieved the final abandonment of all representative intention. In this way he combines in himself the spiritual and technical tendencies of one great branch of Post-Impressionism.

The question most generally asked about Kandinsky's art is: "What is he trying to do?" It is to be hoped that this book will do something towards answering the question. But it will not do everything. This—partly because it is impossible to put into words the whole of Kandinsky's ideal, partly because in his anxiety to state his case, to court criticism, the author has been tempted to formulate more than is wise. His analysis of colours and their effects on the spectator is not the real basis of his art, because, if it were, one could, with the help of a scientific manual, describe one's emotions before his pictures with perfect accuracy. And this is impossible.

Kandinsky is painting music. That is to say, he has broken down the barrier between music and painting, and has isolated the pure emotion which, for want of a better name, we call the artistic emotion. Anyone who has listened to good music with any enjoyment will admit to an unmistakable but quite indefinable thrill. He will not be able, with sincerity, to say that such a passage gave him such visual impressions, or such a harmony roused in him such emotions. The effect of music is too subtle for words. And the same with this painting of Kandinsky's. Speaking for myself, to stand in front of some of his drawings or pictures gives a keener and more spiritual pleasure than any other kind of painting. But I could not express in the least what gives the pleasure. Presumably the lines and colours have the same effect as harmony and rhythm in music have on the truly musical. That psychology comes in no one can deny. Many people—perhaps at present the very large majority of people—have their colour-music sense dormant. It has never been exercised. In the same way many people are unmusical—either wholly, by nature, or partly, for lack of experience. Even when Kandinsky's idea is universally understood there may be many who are not moved by his melody. For my part, something within me answered to Kandinsky's art the first time I met with it. There was no question of looking for representation; a harmony had been set up, and that was enough.

Of course colour-music is no new idea. That is to say attempts have been made to play compositions in colour, by flashes and harmonies. [Footnote: Cf. "Colour Music," by A. Wallace Rimington. Hutchinson. 6s. net.] Also music has been interpreted in colour. But I do not know of any previous attempt to paint, without any reference to music, compositions which shall have on the spectator an effect wholly divorced from representative association. Kandinsky refers to attempts to paint in colour-counterpoint. But that is a different matter, in that it is the borrowing from one art by another of purely technical methods, without a previous impulse from spiritual sympathy.

One is faced then with the conflicting claims of Picasso and Kandinsky to the position of true leader of non-representative art. Picasso's admirers hail him, just as this Introduction hails Kandinsky, as a visual musician. The methods and ideas of each rival are so different that the title cannot be accorded to both. In his book, Kandinsky states his opinion of Cubism and its fatal weakness, and history goes to support his contention. The origin of Cubism in Cezanne, in a structural art that owes its very existence to matter, makes its claim to pure emotionalism seem untenable. Emotions are not composed of strata and conflicting pressures. Once abandon reality and the geometrical vision becomes abstract mathematics. It seems to me that Picasso shares a Futurist error when he endeavours to harmonize one item of reality—a number, a button, a few capital letters—with a surrounding aura of angular projections. There must be a conflict of impressions, which differ essentially in quality. One trend of modern music is towards realism of sound. Children cry, dogs bark, plates are broken. Picasso approaches the same goal from the opposite direction. It is as though he were trying to work from realism to music. The waste of time is, to my mind, equally complete in both cases. The power of music to give expression without the help of representation is its noblest possession. No painting has ever had such a precious power. Kandinsky is striving to give it that power, and prove what is at least the logical analogy between colour and sound, between line and rhythm of beat. Picasso makes little use of colour, and confines himself only to one series of line effects—those caused by conflicting angles. So his aim is smaller and more limited than Kandinsky's even if it is as reasonable. But because it has not wholly abandoned realism but uses for the painting of feeling a structural vision dependent for its value on the association of reality, because in so doing it tries to make the best of two worlds, there seems little hope for it of redemption in either.
