College student Rhapsody Stiggers is one of 38 students at the Boston Conservatory at Berklee taking a dance class that is the first of its kind. Her teacher, Amarisa LeBar, is a current member of the Radio City Rockettes, a famous precision dance team in New York City. Stiggers has been dancing since she was two years old. She has taken many kinds of dance classes. However, the 20-year-old has never had a dance class as difficult as this one. The class is the first for-credit college course taught by a Rockette dancer. The dance instructor teaches the detailed, precise technique the Rockettes are known for. The dancers move and kick together in perfect time.
