Unlike other dance forms, belly dance is quite new to the west. Not only that but it came from a culture not many westerners know much about and most what they think they know is not correct! The language and the way people view the art of dance in general are completely different from East to west.
This makes it very difficult to have a standard vocabulary in English of the dance moves. So many instructors, dancers and musicians just name them what they feel like. This is OK until the moves get to be too many to remember the moves! Or unless you start teaching and everyone knows the same move by a different name!
Things got confusing for everyone instructors and students alike. So what to do?
