Yes, one of the principles of artistic composition is balance. Like all the principles, adapted by artists, it is founded on an instinct of human nature. Have you ever noticed that when a man carries a bucket of water, he holds the free arm away from his body? He does it by instinct, to offset the drag of the bucket on his other arm and to balance his body. Have you ever walked upon the steel rail of a railroad track? Most of us have, I imagine. We tread pretty firmly for a little while, and then we totter. Out go our arms immediately to restore our balance. We walk up and down the deck of an ocean liner, when the sea is rough, and slope our bodies to the movement of the vessel. Why? To keep our balance. If we lose it we are hurled across the deck in a very undignified fashion. On the contrary, what a beautiful spectacle is presented when a good skater balances backward and forward; perhaps an even more beautiful one, when a good dancer who feels the joy of movement sways to the rhythm of the music.
