Art is a diverse range of human activities in creating visual, auditory or performing artifacts (artworks), expressing the author's imaginative or technical skill, intended to be appreciated for their beauty or emotional power.
Art, in its broadest sense, is a form of communication. It means whatever the artist intends it to mean, and this meaning is shaped by the materials, techniques, and forms it makes use of, as well as the ideas and feelings it creates in its viewers. Art is an act of expressing feelings, thoughts, and observations.
