There are two types of aerial dance. In vertical dance a dancer is suspended in a harness from a rope or cable and explores the difference in gravity, weightlessness and varied movement possibilities offered by the suspended state. In the second type a dancer or acrobat intertwines the use of the floor or a wall with their aerial apparatus. The first utilizes the strength and expression of dance with an altered state to communicate contemporary ideas. In the second, the dancer uses dance as a way to indicate that their work is less trick-based than circus arts, and in some cases hopes that disassociating with the circus makes their work appear more contemporary and artistic.
