Writer Brushwork
The use of the brush to create interesting strokes. This gives an abstract quality to the painting, creating near music.
Brushwork (and how you apply dry media such as pastel or graphite) enhances the visual music of your work by giving it a second level of abstraction. If you zoom in on any part of the painting, it becomes an abstract painting in itself. This is one of those other skills that differentiates the real master artists.
