sketch, a rapidly executed kind of pictorial note-taking. The sketch is not usually intended as an autonomous work of art, although many have been considered masterpieces in their own right. Used extensively in the planning of large, complex projects, the sketch allows the artist to visualize quickly the bend of a knee or the sweep of an arm without having to experiment directly on the work itself. See cartoon.
