Brushwork.

Brushwork is the way paint is laid on the canvas — the marks, their direction, their thickness, their freshness, their relationship to the forms they describe. In some traditions brushwork is half the painting; in others it is deliberately invisible. Either way, every painting has brushwork, and the painter must develop a position on what their brushwork is doing. The first lesson of brushwork is that the mark should serve the form. A short, decisive stroke describes a small plane changing direction. A long, sweeping stroke describes a continuous turning form. A scumble describes broken atmospheric texture. A glaze describes deep luminous color. The brush is a tool for describing, not a tool for filling in shapes. Painters who use the same stroke everywhere — uniform pressure, uniform direction, uniform size — produce mechanical and lifeless surfaces. Painters who vary the mark in service of the form produce paintings that feel alive. The second lesson is decision. Strong brushwork is the visible evidence of decisions: marks placed, considered, and left. Weak brushwork is the visible evidence of indecision: marks worked over, fought, smudged, re-cut. Sargent, Hals, and Sorolla are exemplars of decisive brushwork — every stroke looks placed rather than fought. Van Gogh is an exemplar of decisive brushwork in service of energy rather than form: the marks describe the painter's relationship to the subject as much as the subject itself. De Kooning and the gestural abstractionists turned brushwork into the entire subject of the painting. The third lesson is paint quality. Paint should look like itself, not like something it isn't. Thin transparent passages should look transparent; thick impasto passages should look thick. Mid-thickness should look mid-thickness. Painters who lose track of paint quality — sometimes through over-thinning, sometimes through over-mixing, sometimes through repainting — produce surfaces that look dead. The technical principle behind paint quality is fat over lean: in oil painting, each successive layer should contain more oil than the layer below, both for technical longevity and for the freshness of the surface. The fourth lesson is restraint. Bravura brushwork is not the same as good brushwork. Sargent could paint a hand in two strokes because he had already studied that hand at length; the apparent virtuosity rests on careful observation. Painters who attempt to imitate the surface look of bravura brushwork without the underlying observation produce showy, hollow paintings. The discipline of brushwork is the discipline of decision, and decisions require knowledge to make. The fifth lesson is that tradition matters. A Bouguereau painting and a Hals painting are both correctly painted; they just answer different questions about what brushwork should do. A high-finish academic tradition treats the surface as invisible — the painter is showing you the subject, not the paint. An alla prima or painterly tradition treats the surface as visible — the painter is showing you both the subject and the act of painting. Neither is wrong. The painter must know which tradition they are working in and what brushwork that tradition asks for.

- Uniform stroke: every mark the same size, pressure, direction — lifeless surface. - Overworked passages: areas fought into mud through repeated correction. - Brushwork that does not describe form: a flat scribble across what should be a turning plane. - Imitation virtuosity: trying to produce Sargent-style marks without Sargent's observation underneath. - Wrong paint quality: thin where the painting needs thick, thick where it needs thin. - Mixing traditions: tight academic finish in a passage adjacent to alla prima looseness, with no compositional reason for the shift. - Ignoring fat over lean: cracking surfaces, sunken colors, retouch-varnish dependency. - Treating brushwork as ornament: showy marks added for surface interest rather than to describe form.

When Brushwork is in focus, examine the actual surface of the paint — the marks, their direction, their thickness, their freshness. Note specifically: mechanical uniformity where every stroke is the same size and pressure, overworked passages that have been fought into mud, brushwork that does not describe form (a flat scribble across what should be a turning plane), and indecisive paint application. Credit mark variety that serves form — short strokes for small planes, long strokes for sweeping forms — and the alla prima freshness of a passage put down once and left alone. Sargent, Hals, Velázquez, and Sorolla read as masters of brushwork because their marks describe form decisively; Van Gogh because his marks describe energy. When the painter is working in a tight academic tradition, evaluate restraint and surface integrity; when they are alla prima, evaluate vitality and decision.
