Dance is an art form that uses body movement, usually with music, as a form of expression, social interaction, and entertainment or for artistic or religious purposes. It involves movement in space using the whole body or a part of it with a certain rhythm and tempo to express individual feelings or symbols of culture and society. The history of dance studies its evolution over time, from prehistory when humans felt the need for physical communication through rhythmic movements expressing emotions and moods, which also served to ritualize important events. Initially, dance had a ritual component, celebrated in fertility, hunting or war ceremonies, or of various religious nature, where breathing and heartbeats provided an early cadence to dance.
