Brush techniques

The governing concept is using a tool according to its contact area. Even a broad brush can create a fine edge when its narrow side is placed against the surface and moved with light, controlled pressure. Therefore option D is correct. Pressing the brush flat increases the mark, watery paint weakens control, and speed alone cannot guarantee a clean boundary. The method combines orientation with gentle pressure.

The governing concept is matching stroke direction, paint quantity and brush shape to the observed texture. A flat brush carrying only a small amount of light paint can make short horizontal touches that leave gaps, suggesting sparkling, broken ripples. Option A is correct. A wet round brush with vertical lines, dark dots or no brushwork would not describe the horizontal broken highlights of water.

Dry-brush texture depends on removing most paint and moisture before dragging the bristles across the surface. The remaining small amount catches only parts of the texture and leaves broken marks. If the brush carries too much paint or moisture, it fills the gaps between bristles and produces a solid band. Thus option B is correct; brush size, a rough surface and light pressure do not explain this result as directly.

The governing concept is controlled layering. A wet first layer can be disturbed by the next brushstroke; its pigment may lift or mix with the second colour, spreading beyond the intended boundary and making the edge blurry. Therefore option C is correct. The second layer is not always transparent, the brush cannot become stronger through layering, and wet paint does not make paper shine by itself. Waiting for suitable drying improves clarity.

The governing concept is uniform brush loading. A stroke becomes thick at the beginning and watery later when the brush does not carry a consistent balance of pigment, medium and moisture. As the stronger mixture is used up, excess water reaches the surface and weakens the mark. Thus option D is correct. Paper size and hand direction are not the main causes, and colour alone does not describe the needed moisture balance.

The governing concept is emphasis through contrast. Crisp, controlled strokes create a clear edge and stronger visual information in the focal area, while softer strokes around it reduce competing attention. Therefore, option A directs the viewer’s eye most effectively. Equal detail everywhere gives no priority, and using only thick or only blurred strokes throughout does not create a useful focal contrast.

The governing concept is variation in brushwork. Different directions, lengths, pressures, and rhythms can describe changes in form and texture. If every stroke is identical and parallel, the surface loses visual variety and appears mechanically repetitive, so option B is correct. Uniform strokes do not erase colour, break the brush, or change the physical size of the paper.

The governing concept is edge control in composition. Hard edges are visually sharper and often attract attention or define an important form. Soft edges reduce emphasis, suggest atmospheric distance, or help one shape merge gently into another. Thus option C correctly identifies the combined purposes of depth, attention, and form. The other choices concern neither the visual role nor the handling of edges.

The governing concept is control of brush contact. A round brush makes a fine mark when only its pointed tip touches the surface, but applying suitable pressure bends and spreads more of the bristles, increasing the contact area and producing a broader stroke. Therefore option D is correct. The handle, an unloaded brush, or movement in the air cannot create a painted broad mark.

The governing concept is coordinated stroke control. Brush speed must suit the paint’s consistency and the amount loaded on the bristles. Moving too slowly can leave excess paint and cause pooling, while moving too quickly may produce a weak or broken mark. Option A is correct because a suitable speed maintains continuous flow without accumulation. The words “always” in B and C make them false.

The governing concept is smooth, controlled paint application. Paint with suitable consistency spreads predictably, and light, even strokes reduce ridges made by individual bristles. Option B is correct because it limits visible streaking without damaging the surface. Hard scraping can disturb the dry layer, a completely dry brush may leave stronger marks, and repeated rubbing in every direction can create uneven texture and overwork the paint.

The governing concept is tool condition and mark control. A fine line depends on the bristles meeting in a clean point and releasing paint in one controlled path. If the tip is split, separate bristle groups may deposit parallel marks or leave gaps, so option D is correct. A damaged tip does not necessarily darken or lengthen the line and has no direct effect on drying speed.

The governing concept is observing texture in relation to form. Fur follows the underlying body, so its direction, curvature, density, and apparent length change across different areas. Option A is correct because varied strokes describe that growth pattern and make the texture appear natural. Fur is not always circular, a brush can represent it, and paint does not inherently prevent directional variation.

The governing concept is deliberate edge control. A hard edge is preserved when the paint is placed with a controlled stroke on a sufficiently dry surface and the boundary is not softened afterward. Therefore option B is correct. Repeated wetting, a damp brush, or spreading paint outward introduces diffusion and makes the boundary softer, which is the opposite of the intended result.

The governing concept is that stroke direction affects visual movement and surface texture. When a painter repeatedly changes direction in the same area, the marks overlap irregularly, so the eye notices activity, variation, and a restless or complex texture. Option C is correct. A, B, and D are not necessary results: directional changes do not always smooth, create transparency, or remove marks.

The governing concept is air entrainment during paint preparation. If colour is whipped rapidly and repeatedly with a brush, air becomes trapped in the liquid and appears as small bubbles when the layer is spread. Option D is therefore correct. A brush’s colour, the paper’s shape, or the fact that the brush is new does not normally explain bubbles. Gentle mixing helps prevent them.

The governing concept is that brush orientation controls the area of bristle contact. Rotating the brush brings a different side, edge, or point onto the surface, changing the width, contour, and direction of the mark. Option B is correct. Rotation does not by itself make the colour lighter, increase paper thickness, or shorten the handle.

The governing concept is precision through tool size, moisture, and pressure control. A small pointed brush places colour accurately; reduced moisture limits uncontrolled spreading, and light pressure prevents an overly wide mark. Option C combines all three corrections. A and D add fluid or bulk, while B makes the paint move faster and reduces control.

The governing expressive concept is that visible direction, speed, and variation communicate movement. Quick broken strokes leave lively changes in direction and texture, so the viewer senses energy and rapid action. Option D is correct. Identical dots, static horizontal bands, and uniformly softened edges reduce directional activity and therefore suggest stillness or softness rather than fast movement.

The governing learning concept is controlled observation: record the variables that cause a stroke and the visual result they produce. Brush type, pressure, angle, and moisture can be compared with the resulting mark, so Option B supports repeatable learning. A, C, and D may be useful records, but alone they cannot explain why one stroke worked differently from another.

The governing principle of an even wash is controlled moisture and an even distribution of pigment. At the lower edge, excess water and paint can collect as a bead; when it dries, the pigment concentrates and forms a dark band. Therefore, option D is correct: the artist should remove the accumulated liquid with a clean, slightly damp brush. A white paper, small brush, or lack of paint does not by itself create this tide mark.

Dry brushing depends on a small amount of relatively dry paint and light pressure. The bristles then catch mainly on the raised or textured parts of the surface, leaving broken marks rather than a solid coat. Option A is correct because removing excess water and pigment restores this effect. More water, heavy pressure, soaking, or dipping to the ferrule would make the stroke wetter and more opaque, so those choices contradict the technique.

Double loading works by placing two separate colours on different sides or regions of the brush so that they meet gradually during the stroke. Excessive back-and-forth mixing on the palette destroys that separation before painting begins, causing muddy colour. Option B is therefore correct. A long handle, dry paper, or the simple fact that the colours differ does not explain the unwanted mixing as directly.

Line width is governed by the brush’s contact area, pressure, angle, and movement speed. If the artist intermittently presses harder or changes the angle, more bristles touch the paper and the line becomes thicker. Option C is correct because inconsistent pressure and angle directly change that contact area. Colour naming, paper size, and the presence of a ferrule do not normally cause periodic changes in line width.

Scumbling is based on broken, irregular application in which small gaps allow the underlying colour or texture to show through. If the lower layer has disappeared, too much opaque paint or pressure has probably been used. Option A is correct: reduce the paint load, use light pressure, and make irregular strokes. A thick coat, wetter surface, or continuous pressing would cover the underlayer even more completely.
