Dance can express what words cannot, whether it's the triumphant joy in a football player's posttouchdown pirouette or the passionate tango used to notify roommates that the basement is flooding. Transmit tidings with twinkling toes thanks to today’s Groupon: for $20, you get your choice of four dance classes at Farfesha Belly Dance in the Bear Canyon Plaza (a $40 value). Classes are held throughout the week and each meet for one hour; customers do not have to attend consecutive classes, but all four classes must be used within a span of six months. Customers should call ahead to find out the most up-to-date schedule.

Farfesha takes its name from an Egyptian term that means “joyous laughter,” and the studio strives to make each person’s dance experience an exuberant adventure of self-discovery. Inside the undulating-movement emporium's roomy confines, women learn to increase their flexibility and follow their torsos' dance leads during myriad classes taught by a team of talented dancers.

Oft-ignored body parts are trained to gyrate healthily during a beginning belly-dance class, which introduces first-time stomach shakers to the art's basic moves. Intermediate and advanced classes progress into more complicated steps and also throw in zills and props such as veils and canes. Shake and groove to body-boogying tunes in a Zumba class, or flow into a flamenco session, steeped in Spanish culture and devoid of pink bird feathers. Hula imparts graceful swaying to tropical dancers, and newly added salsa classes combine upbeat songs with mild, medium, and hot footwork.
