Aerial dance is the broad term for a style of modern dance that incorporates the use of hanging equipment, also called aerial apparatuses. Aerial silks (also known as aerial fabric, aerial tissue, aerial ribbon, or aerial curtain), trapeze, lyra (aerial hoop, cerceau), aerial rope (corde lisse, Spanish web), aerial sling (aerial hammock), and aerial net are a few of the more popular apparatuses, although Fractal Tribe is also known to invent their own equipment. It is an incredibly demanding art form that requires a high degree of strength, power, flexibility, courage, and grace to master.
