What is art, and who has the right to define it, are very difficult questions to answer. Artists often produce works of art that are controversial, and sometimes work has been banned because it is deemed to be offensive. But what one person finds offensive, another may interpret as a powerful work of art. The measure of art is, like beauty, in the eye of the beholder. Different cultures around the world have developed their own artistic traditions and styles.
Art is the expression of emotion, and a reflection of the world the artist lives in.
Artists are people who develop particular artistic skills, either through training or years of work, or both. Most of us are involved in the arts in some way or other without even thinking about it. Artists create works of art in their chosen discipline or medium, such as opera or sculpture. The great thing about the arts is that there are so many different disciplines, there's bound to be something for everyone.
