Dancing is one of the universal forms of expression and art around the world, along with music and some others. In fact, dancing serves many functions in the past and present, not just recreation. In past societies and lower-tech modern ones, dancing is sometimes used to impress others and convey a message, or even be a part of a rite of passage. Many dancers wear certain outfits or accessories during their work, from tribesmen in rural Africa to Native Americans performing war dances or rain dances. Some dancing is done with the dancer using noise-making accessories or handheld decorations to accentuate their dance and give it extra meaning.
In the modern context of dancing in North America and Europe, meanwhile, dancing is largely recreational, and can be a source of entertainment, exercise, and bonding with others. For these reasons and more, dance classes can be taken nearly anywhere, and dance classes can be done at local dance studios when an interested party looks them up.
