_______ creates movement in a piece.
What are the choices
This can't be answered here. An artist may use any number of techniques to prompt the viewer's eye to move. Your course or program seems to have one specific one in mind. I'd advise that you re-read your text materials or class notes very carefully to see exactly what they have in mind.
One element that creates movement in a piece is the use of line. Lines can be used to guide the viewer's eyes through the composition, leading them from one point to another and creating a sense of motion. Different types of lines, such as diagonal lines, curves, or jagged lines, can convey different types of movement.
To create movement with lines in a piece, one approach is to consider the direction and placement of the lines. Diagonal lines, for example, often evoke a sense of action and dynamism. By incorporating diagonal lines into your composition, either through the objects or the arrangement of shapes and elements, you can create a visual flow and suggest movement. Additionally, pairing this with other techniques like repetition, overlapping, or variation in line thickness can enhance the perception of movement.
Another way to create movement is through the use of implied motion. This involves suggesting movement without actually depicting it. For instance, you can use elements like blurred edges, streaks, or layers to imply the passage of time or the movement of objects. By strategically placing these elements within your composition, you can give the viewer a sense of action and create a dynamic visual experience.
It's important to experiment with different techniques and observe how they affect the overall sense of movement in your composition. Remember to consider the elements that you want to convey and use them in a way that supports your intended message or expression. Ultimately, creating movement in a piece is a combination of deliberate design choices and the interpretation of the viewer.
