Dance is the art of movement of the body, usually rhythmically and to music, using prescribed or improvised steps and gestures. "A dance" is any one prescribed sequence of such movements, or the music to which it is performed, or an event at which it takes place. Dance may also be regarded as a form of nonverbal communication recognisable in other animals; in bee dances and behaviour patterns such as mating dances.A wedding is a ceremony where two people are united in marriage. Wedding traditions and customs vary greatly between cultures, ethnic groups, religions, countries, and social classes. Most wedding ceremonies involve an exchange of wedding vows by the couple, presentation of a gift (offering, ring(s), symbolic item, flowers, money), and a public proclamation of marriage by an authority figure or leader. Special wedding garments are often worn, and the ceremony is sometimes followed by a wedding reception. Music, poetry, prayers or readings from religious texts or literature are also commonly incorporated into the ceremony.
