Find the best modern dance lessons, classes, and instructors at HeyKiki and learn modern dance. The expressionist movement of modern dance emerged around the early 20th century as a revolt against classical ballet. Pioneered by Isadora Duncan, who viewed ballet as an ugly dance form, modern dance is much more laid back. Rather than tight moves and line choreography, modern dance involves free movement of the torso, unordinary costumes and extended use of the dancer's bare feet. Expect to get a little interpretative; welcome to the modern age.
