Dance (from French danser, perhaps from Frankish) is an art form that generally refers to movement of the body, usually rhythmic and to music, used as a form of expression, social interaction or presented in a spiritual or performance setting.
Dance categories by number of interacting dancers are mainly Solo dance, Partner dance and Group dance. Dance is performed for various purposes like Ceremonial dance, Erotic dance, Performance dance, Social dance etc.
Many early forms of music and dance were created and performed together. This paired development has continued through the ages with dance/music forms such as: jig, waltz, tango, disco, salsa, electronica and hip-hop. Some musical genres also have a parallel dance form such as Baroque music and Baroque dance whereas others developed separately: classical music and classical ballet.
Although dance is often accompanied by music, it can also be presented independently or provide its own accompaniment (tap dance). Dance presented with music may or may not be performed in time to the music depending on the style of dance. Dance performed without music is said to be danced to its own rhythm.
