A gesture drawing is completed quickly – often in short timed durations, such as 20, 30, 60 or 90 seconds – using fast, expressive lines. Gesture drawings capture basic forms and proportions – the emotion and essence of a subject – without focusing on detail. Due to their rapid completion, they are a great way to record movement and action, as well as increase your drawing speed, confidence and intuitive mark-making skill. Gesture drawings are best completed with smooth, easily applied mediums (chunky graphite pencils, charcoal sticks, pastels, soft brushes dipped in Indian ink, for example), without the use of an eraser. They are often completed on large, inexpensive sheets of paper, where you can move your arm fluidly, be bold with mark-making, and not worry about mistakes. As with blind drawings, gesture drawing is an ideal warm-up activity.
When we first picked up a pen or pencil and started making marks on paper, we began with line. Whether self-taught, through trial and error, or guided by others, we learned how line defines form, creates structure, divides a frame, traces contour, creates tonal variation (cross-hatching, for example) and leads the eye from one part of a work to another. Initially a mechanism for getting outlines onto paper – identifying edges – we begin to applaud lines for their own merit: celebrate their presence…whether a quiet flick of charcoal on paper or a streak of graphite.
Here is a collection of line drawings from famous and less well known artists, to inspire high school Art students and teachers. This section is continually updated. Enjoy!
A planar analysis drawing simplifies complex curved surfaces into flat planes, using straight lines. This process helps students to think about the underlying structure of objects and results in an analytical drawing, that is rather mechanical in appearance.
