Drawing instruction is a training towards perception, exact observation and exact presentation not of the outward appearances of an object, but of its constructive elements, its lawful forces-tensions, which can be discovered in given objects and of the logical structures of same-education toward clear observation and clear rendering of the contexts, whereby surface phenomena are an introductory step towards the three-dimensional.

A parallel between color and music can only be relative – just as a violin can give warm shades of tone, so yellow has shades, which can be expressed by various instruments.

The circle is the synthesis of the greatest oppositions. It combines the concentric and the eccentric in a single form and in equilibrium. Of the three primary forms, it points most clearly to the fourth dimension.

Whether the psychological effect of color is direct...or whether it is the outcome of association, is open to question. The soul being one with the body, it may well be possible that a psychological tremor generates corresponding one through association.

As a picture painted in yellow always radiates spiritual warmth, or as one in blue has apparently a cooling effect, so green is only boring.

Color is the keyboard, the eyes are the harmonies, the soul is the piano with many strings. The artist is the hand that plays, touching one key or another, to cause vibrations in the soul.

An empty canvas, apparently really empty, that says nothing and is without significance – almost dull, in fact – in reality, is crammed with thousands of undertone tensions and full of expectancy. Slightly apprehensive lest it should be outraged.
