The painter of this piece, artist William Schwartz, said, "In both music and art, I believe that the great thing is the creation, in an individual way, of harmony. In art . . . harmony may be of three sorts — of color, of form, and of line. Mastery of one of these elements is unsatisfactory . . . I strive for the mastery of all three." 

What harmonies do you think Schwartz achieved in this painting -- color, line, form? In what ways?

Is the style of this painting more abstract or more realistic than the style of his Outskirts of Galena painted two years earlier?
