121. What has been said about the composition of Lines and Outlines
applies equally well to the composition of Areas, so far as they
are distinguished and defined by outlines. We will now proceed to
consider areas as distinguished and defined, not by outlines, but by
tone-contrasts. The composition of lines and outlines is one thing,

is another. In putting lines and outlines together we draw. The point
of view is that of drawing. In putting tones in different positions,
measures, and shapes we paint. The point of view is that of the
painting.
