Artistic Characteristics of Sketching

The monochromatic drawing by charcoal, pencil, pen, etc., to draw the light and darkness of an object with lines is called sketching. Monochrome watercolor and monochrome oil painting can also be regarded as sketching; traditional Chinese white drawing and ink painting can also be called sketching. Usually, the term "drawing" refers to pencil and charcoal drawings. Sketching is the foundation of all painting, and it is a necessary stage in the study of the art of painting.　Sketching is usually done by methods that leave marks on a flat surface, such as charcoal, pen, paintbrush, ink, and paper. Outline and line are the general terms for sketching. Sketching has a natural rhythm. Different strokes of the brush create different relationships and rhythms of line and crosscut, active and passive surroundings, planes, volumes, tones, and textures.

Drawing is a formal artistic creation that uses monochromatic lines to express things in the intuitive world, as well as to express ideas, concepts, attitudes, feelings, fantasies, symbols, and even abstract forms. Instead of focusing on totality and color, as in colorful paintings, it focuses on structure and form.
