Disco is a dance style performed in Dancing with the Stars.
Disco music developed in the early 1970s to cater to nightclub audiences. For this reason, there is a mostly consistent beat to keep people moving on the dance floor. The basic tempo of disco is approximately 120 beats per minute, 4/4 time signature and four-on-the floor rhythms.
In the early years, dancers in discos danced in a "hang loose" or "freestyle" approach. At first, many dancers improvised their own dance styles and dance steps. Later in the disco era, popular dance styles were developed, including the "Bump", "Penguin", "Boogaloo", "Watergate" and "Robot". By October 1975 the Hustle reigned.
During the disco era, many nightclubs would commonly host disco dance competitions or offer free dance lessons. Some cities had disco dance instructors or dance schools, which taught people how to do popular disco dances such as "touch dancing", "the hustle", and "the cha cha". The pioneer of disco dance instruction was Karen Lustgarten in San Francisco in 1973. Her book The Complete Guide to Disco Dancing (Warner Books 1978) was the first to name, break down and codify popular disco dances as dance forms and distinguish between disco freestyle, partner and line dances. The book topped the New York Times bestseller list for thirteen weeks and was translated into Chinese, German and French.
In Chicago, the Step by Step disco dance TV show was launched with the sponsorship support of the Coca-Cola company. Produced in the same studio that Don Cornelius used for the nationally syndicated dance/music television show, Soul Train, Step by Step's audience grew and the show became a success. The dynamic dance duo of Robin and Reggie led the show. The pair spent the week teaching disco dancing to dancers in the disco clubs. The instructional show which aired on Saturday mornings had a following of dancers who would stay up all night on Fridays so they could be on the set the next morning, ready to return to the disco on Saturday night knowing with the latest personalized dance steps. The producers of the show, John Reid and Greg Roselli, routinely made appearances at disco functions with Robin and Reggie to scout out new dancing talent and promote upcoming events such as "Disco Night at White Sox Park".
