Belly dance:

Native to North Africa, Asia and the Middle East, belly dancing (Arabic:raqs al sharqiرقص شرقي) is based on one of the oldest social dances in world history. Support for this theory stems from similarities between poses from the modern dance form and those depicted in ancient Egyptian art.[citation needed]
There are two forms of belly dancing. The first is called raqs baladi, a social dance performed for fun and celebration by men and women of all ages, usually during festive occasions such as weddings and other social gatherings.
The second form, the more theatrical version and the one most popular in America today, is called raqs sharqi. Like raqs baladi, raqs sharqi is performed by both male and female dancers.
In regions where belly dancing is native, boys and girls learn it informally from an early age by observing and imitating their elders during family/community celebrations and gatherings with friends.[citation needed] Today, these ancient dance forms are taught in classes throughout the world where skilled dancers/teachers share the knowledge that has been passed down to them.
