There are five common functions of art: Personal, Social, Spiritual, Educational and Political. Your studio works should strive to encompass more than one of these areas, but you are not required to do all of the areas.
Five Areas:
Personal function: to express personal feelings. Perhaps the artist wanted to remind viewers of personal family tragedy, or perhaps he just wanted to tell them to appreciate what they had, and to live each day as if it were their last.
Social function: to reinforce and enhance the shared sense of identity of those in family, community, or civilization, for example, festive occasions, parades, dances, uniforms, important holidays or events.
Spiritual function: to express spiritual beliefs about the destiny of life controlled by the force of a higher power.
Educational function: symbols and signs to illustrate knowledge not given in words
Political function: to reinforce and enhance a sense of identity and ideological connection to specific political views, parties and/or people.
