A sketch is a rapidly
executed freehand drawing that is not usually intended as a finished
work. A sketch may serve a number of purposes: it might record something
that the artist sees, it might record or develop an idea for later use or it
might be used as a quick way of graphically demonstrating an image, idea or
principle.

Sketches can be made in any drawing medium. The term is most often applied
to graphic work executed in a dry medium such as silverpoint, graphite, pencil, charcoal or pastel.
It may also apply to drawings executed in pen and ink, digital input such as
a digital pen, ballpoint pen, marker pen, water colour and oil
paint. The latter two are generally referred to as "water colour
sketches" and "oil sketches". A sculptor might model
three-dimensional sketches in clay, plasticine or
wax.

Sketching is generally a prescribed
part of the studies of art students. This generally includes making sketches (croquis)
from a live model whose pose changes every few minutes. A "sketch"
usually implies a quick and loosely drawn work, while related terms such
as study, modello and "preparatory drawing" usually refer
to more finished and careful works to be used as a basis for a final work,
often in a different medium, but the distinction is imprecise. Underdrawing is
drawing underneath the final work, which may sometimes still be visible, or can
be viewed by modern scientific methods such as X-rays.
Most visual artists use, to a greater or lesser degree, the sketch as a
method of recording or working out ideas. The sketchbooks of some individual
artists have become very well known, including those of Leonardo da
Vinci and Edgar Degas which have become art objects in their own
right, with many pages showing finished studies as well as sketches.
The term "sketchbook" refers to a book of blank paper on which an
artist can draw (or has already drawn) sketches. The book might be purchased
bound or might comprise loose leaves of sketches assembled or bound together.
Sketching is also used as a form of communication in areas of product
design such as industrial design. It can be used to communicate
design intent and is most widely used in ideation. It can be used to map out
floor plans of homes.
The ability to quickly record impressions through sketching has found
varied purposes in today's culture. Courtroom sketches record scenes
and individuals in law courts. Sketches drawn to help authorities find or
identify wanted people are called composite sketches. Street artists in
popular tourist areas sketch portraits within minutes.
