BSEH Secondary Drawing key terms

A line that traces the outer edge or a visible boundary of a form, describing shape without shading. Contour drawings record edges, overlaps and changes of plane to explain three-dimensional structure.

The thickness or darkness of a drawn line. Varying weight creates emphasis, shows nearness or distance, and separates foreground from background in a sketch.

The size relationship between parts of a drawing and the whole, or between one object and another. Correct proportion makes objects look believable even when style is loose.

A measuring technique in which the artist holds a pencil at arm's length to compare lengths, angles and alignments in the subject before marking them on paper.

A vertical reference line, real or imagined, used to check whether points in a subject sit directly above or below one another. It corrects tilt and misalignment in free-hand drawing.

The level of the viewer's eye, drawn as a horizontal line across the picture. All vanishing points for level lines lie on it, and it fixes the height of the viewpoint.

The height of the observer's eyes relative to the scene. Objects above eye level are seen from below and objects below are seen from above, so it controls apparent perspective.

The point on the horizon line where parallel lines receding from the viewer appear to converge. One-point and two-point perspective each use a fixed number of them.

The apparent shortening of a form that points towards or away from the viewer, such as an arm extended forward. It compresses lengths and shifts overlaps in the drawing.

The imaginary flat surface between the artist's eye and the subject, on which the scene is projected. It is the mental frame that the drawing paper represents.

The arrangement of shapes, values and spaces within the picture format. A sound composition guides the eye, balances weight and keeps the subject readable.

A compositional guide that divides the picture into a three-by-three grid and places key elements near the intersections rather than at the centre, giving a livelier balance.

The area of a picture that draws attention first, usually through the strongest contrast, sharpest detail or highest saturation. Other elements should support it, not compete with it.

A rapid sketch that captures the action, weight and direction of a pose rather than its outline. Long sweeping strokes record movement and rhythm in a few seconds.

The single flowing curve that summarises the main thrust of a figure's pose, from head through torso to supporting foot. It keeps a figure dynamic and structurally coherent.

The use of strong contrasts of light and dark to model form and suggest volume. It relies on a clear light source and a graded transition from highlight to core shadow.

The darkest band on a form where the surface turns away from the light, before reflected light begins. Its position and shape describe the curvature of the object.

Weak light bouncing from nearby surfaces back into the shadow side of an object. It keeps shadows transparent and prevents them from reading as flat black holes.

The shadow an object throws onto the ground or another surface. Its direction, length and edge softness depend on the light source and on the distance to the receiving surface.

The relative lightness or darkness of a tone, independent of its hue. A well-organised value pattern makes form and depth readable even in a monochrome study.

The degree of difference between the lightest and darkest tones in a drawing or design. High contrast creates drama and emphasis, while low contrast produces softness and unity.

A shading technique using parallel lines to build tone. Closer lines give darker values, and crossing sets of lines at an angle produce cross-hatching.

The visual or tactile quality of a surface, such as roughness, gloss or grain. In drawing it is suggested through mark-making, edge quality and patterns of light and dark.

A drawing of inanimate objects such as fruit, vessels or drapery arranged for study. It trains observation of proportion, light, texture and spatial relationships.

A standard idealised proportion in which the total body height equals about eight head lengths. It gives a reliable starting framework for figure drawing and anatomy study.

A circular arrangement of hues showing their relationships. Primary colours sit opposite their complementary partners, and adjacent hues form analogous families used in colour planning.

Hues lying opposite each other on the colour wheel, such as red and green. Mixed as pigment they dull each other; placed side by side they create maximum visual contrast.

Hues that sit next to each other on the colour wheel, sharing an underlying hue. They produce calm, harmonious schemes with limited contrast.

A pleasing relationship among the colours in a work, achieved through shared hue, balanced value or controlled saturation. Harmony does not require similarity; it requires intention.

The effect in which a colour appears to change depending on the colours surrounding it. A grey looks warmer against blue and cooler against orange.

A tint is a colour lightened by adding white; a shade is a colour darkened by adding black. Together with tone, they extend a single hue into a usable range of values.

A folk painting tradition of the Mithila region of Bihar, done with fine line work, dense pattern filling and natural pigments. Themes include mythology, nature and ritual occasions.

A tribal wall-painting tradition of Maharashtra using white rice paste on earth-coloured ground. Figures and motifs are built from triangles, circles and squares with rhythmic repetition.

Art made within a community's living tradition, passed down through practice rather than formal training. It often uses local materials, symbolic motifs and flat decorative treatment.

A small-format, finely detailed painting tradition associated with Indian court ateliers and manuscript illustration. It combines delicate brushwork, flat colour and stylised perspective.

A repeated visual unit such as a flower, leaf, animal or geometric shape used in ornament and design. Motifs are combined and repeated to create pattern and rhythm.

Decorative detail added to a surface or border to enrich it, drawn from floral, geometric or traditional sources. Good ornament respects the structure it decorates rather than hiding it.

A principle of design in which repeated or related elements create a sense of movement through the eye. Regular, alternating or progressive repetition all produce rhythm.

The hand-drawn construction of letters and words with consistent height, spacing and stroke weight. Even spacing and a stable baseline matter more than decorative flourishes.

A spray or liquid applied to a finished drawing to bind the pigment and reduce smudging. It is used outdoors or in a ventilated area because the fumes are harmful.

A drawing medium made from carbonised wood, valued for deep blacks and easy blending. It smudges readily, so it needs a fixative and careful handling on the sheet.
