Strokes in art refer to the marks made by a brush, pencil, or other tools on a surface, such as canvas or paper. These strokes can vary in size, shape, and texture, contributing to the overall composition and style of a piece. Artists often use different techniques to create distinct effects, such as blending, layering, or stippling. The way strokes are applied can convey emotion and movement, influencing how viewers perceive the artwork. For example, Vincent van Gogh is known for his expressive, swirling strokes that add dynamism to his paintings. Understanding strokes helps appreciate the skill and intention behind various art forms.
