Dance can express what words cannot, whether it's the triumphant joy in a football player's post-touchdown 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 three private and three group dance classes of your choosing (a $189 value) at Rocket City Dance Club on Artie Street.

Rocket City Dance Club limbers limbs of all levels with classes in a multitude of styles, including rhythm and Latin, smooth and standard, and country western dances. Swing students are swung into club-ready shape while Cha Cha amateurs and Samba starters get their hips hopping in no time. Classes in smooth and standard dances like the Waltz, Tango, Fox Trot, and Lemur Gallop reflect a more Continental cast, providing instruction in both competitive and non-competitive forms of frolic. A friendly and accommodating instructor will play the role of partner for the un-pre-paired, while group classes are great for meeting cavorting comrades. Call ahead to schedule a lesson in any style.
