Musicians on the street corner in the South Side express their art in song. The grand designs of downtown skyscrapers celebrate an era of wealth and prosperity in the city. Graffiti on North Side underpass walls express political viewpoints. Indian women at a Hindu temple in Monroeville paint their hands and feet with traditional Mendhi designs to recognize their upcoming marriages. Neighboring houses of worship on Fifth Avenue in Oakland use art to express faith.
Some art is an act of individual expression.
Perhaps the poet tries to describe an elusive emotion using a particularly evocative combination of words. A dancer or musician may convey emotion without using words at all. The painter or photographer captures a single frame of time and lets others in the world see the image as it appeared in their own mind's eye. Some artists intentionally exaggerate an image. This is called caricature.
