Furia: the impulsive act of creation. A “true” drawing is created with little thought for the drawing is a document or trace of images which pop in and out of the artist’s mind. In more popular culture, it is metaphorically represented in cartoons when a light bulb goes off above someone’s head as soon as a thought enters their mind. It is the same with art. A thought quickly enters the artist’s mind, and it is necessary to get it down on paper while it is still fresh. If the artist stalls or thinks it through, the image may become stale and lose its spontaneity. How is this visualized in the final drawing? If the artist created it without much thought, the composition will not be fully worked out. There may be a lack of symmetry, balance, repetition of shape, line, or color. Some parts may be detailed while others may be minimally defined or left empty. Large areas of the paper may be blank, implying that the artist lost interest or the idea grew stale before he got to these other parts.

Sprezzatura: the speed with which a work of art is finished. The drawing will demonstrate that the artist was in a hurry. Lines may look rushed and unfinished. Analytic lines may become sloppy and resemble dots, dashes, or squiggles. The artist may have been so rushed through the drawing process, either due to internal or external circumstances, that many areas may be illegible. Again, look at the quality of the lines as evidence of speedy process.
