I would suggest this as a new game to students, one giving another two or three lines drawn in a panel at random, the problem being to make harmonious arrangements by the introduction of others radiating in sympathy.
Often in a picture certain conditions are laid down to start with; something as ugly as our original group of lines drawn at random has to be treated pictorially, and it is by means such as here suggested that its discordancy can be subdued and the whole brought into harmony with the shape of your panel. The same principles apply in colour, discordant notes can be brought into harmony by the introduction of others related to both the original colours, thus leading the eye from one to the other by easy stages and destroying the shock. Somewhat in the way a musician will take you from one key into another very remote by means of a few chords leading from the one to the other; whereas, had he taken you straight there, the shock would have been terrible. As it is, these transitions from one key into another please and surprise one, and are very effective.

SHOWING HOW LINES UNRELATED CAN BE BROUGHT INTO HARMONY BY THE INTRODUCTION OF OTHERS IN SYMPATHY WITH THEM.
A. LINES DRAWN AT RANDOM.
B. TAKING LINE 1-2 AS DOMINANT LINE.
C. AS AT B BUT WITH ADDITION OF MASSES TO COVER LINES CROSSING AND RESTORE BALANCE
D. TAKING LINE 3-4 AS DOMINANT LINE
