In burlesque, there are four basic dance moves: the bump, the grind, the shimmy, and the shake. In bellydance, there are apparently a whole lot more: the prayer, taxeem, hand floreo, undulation, pivot, choo-choo, and so forth. All are listed as fundamentals of the sensuous tribal bellydance style taught at the new Skin Deep Dance Studios. Sponsored by those reliable importers of musical exotica, Six Degrees Records, the studios grand opening features free classes all day in Viniyoga, Jazz, Modern, punk rock yoga, Bollywood, and of course, tribal bellydance.
