Hopper’s Early Sunday Morning, 1930, is a perfectly composed painting.
If you were to draw an imaginary line down the center of the painting, you
would have an equal balance and visual weight of the building with its
distribution of windows and doors. For every window on the left, there is a
corresponding window on the right. For unity, the first and second floors are
of equal height. However for variety, the first floor of the building is
green; the second floor is red. Additionally, the windows are all rectangular
and identical in height. The same is true for the first floor with the shapes
and sizes of doors and plate glass windows. In order to maintain the viewer’s
level of interest, Hopper needed to introduce variety. While both the fire
hydrant and the barber pole are verticals and equidistant from the imaginary
centerline, there is variety in their coloration and height. Variety is also
apparent in the first floor. If we follow the distribution of doors and
windows, we see an A (window) B (door) A B A B AA B A rhythm from
left to right.
