A path for a painter is like a melody line or chord progression for a composer. It's our way of getting the viewers' attention then guiding their eyes to the areas where we want them to travel. We use a variety of methods to achieve this. Look at this painting by
Jennifer McChristian. Where do your eyes first go?
The first thing I see is two people walking toward us. After that I notice the other two people, cars, and then the overall scene. As an afterthought, my eye goes to the red sign in the upper left of the painting then to the rear of a truck exiting the scene. The sign and truck bring my eyes back to the figures.
That's the visual path.
Experiencing this work is like feeling a chord progression pulling us from one area to another before we come back to the major key. To keep the chord moving, the artist uses temperature contrast (the warm colors used in the building, figures and truck within the cooler colors of the buildings, street and sky), isolation (the dark figures within a light space), and one-point perspective (angles of the street and buildings vanishing to a single point).
That's better than a bagel with cream cheese and jam.
