Whether you are dancing a slow dance such as the waltz or an upbeat dance like the jive, you need to choose attire that you can move easily in and won't get tangled up around your partner. For example, consider choosing a dress made of silk; it flows easily and doesn't tangle. Remember that although ballroom dancing is a formal and elite event, your dress doesn't have to be covered in heavy sequins, jewels, or feathers. Ballroom Dancing - The Cha-Cha The London dance instructor Pierre Lavelle, who was responsible for having the Cuban Rumba declared the official Rumba, while on a visit to Cuba, had noticed that sometimes there were extra beats added to the Rumba. Upon his return to England he taught these steps as a completely new dance. The English language adopted this term from the Latin word "ballare", meaning "to dance". Ironically, this also serves as a base for words like "ballerina" and "ballad". Ballrooms were a very popular source of entertainment before the days of cable television, internet, or satellite radio. This light-hearted dance involves concentrated footwork and lifting or twirling your partner. It became popular in the 1920's and was originally invented at the Savoy Ballroom in New York. A spin-off of the Lindy Hop, the swing dance combined fast twirls and steps to the beat of jazz music. Today, the swing dance is still performed in an old-fashioned manner using the exact same techniques developed decades ago. However, while working on their bid to get into the Olympics, the group was setting up their bylaws and came to the conclusion that there was a definite need for guidelines for the large number of Social Dancers and American Style dancers, as well as the International Style competitors. While working to help the dancers compete nationally and internationally they also helped to set things in motion to insure the availability of floors, music and locations for a group that turned out to be the backbone of the USABDA, the Social Dancers. Several colleges now offer ballroom dancing as a credit for physical education, and often they will invite the public to attend the classes. These classes are typically about one hour long, once or twice a week, and last for about four to five months. Although the cost depends on the particular institution, ballroom dance classes offered here are usually very inexpensive or free.
