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. The early years for the USABDA only saw a small number of members in New York state, a few in the Washington, DC area and a small number on the west coast. You have to find the perfect dress (or suit and tux if you're a guy), perfect shoes, and coordinate your hair and makeup for a complete look. However, getting ready for an evening of ballroom dance is slightly more complex than dressing for the prom. While the concept is the same, a lot of factors need to be taken into consideration when choosing ballroom dance clothing and shoes. The wealthy section of Cuban society preferred the Danzon, which is an even slower Rumba using very small steps and more subtle hip movements. The modified version of the Rumba known as the Son was introduced to Americans in 1913. In the late 1920's Xavier Cugat formed an orchestra specializing in Latin American Music which really didn't develop a following until around 1929. The most often told story is that the dance was made popular by a young man named Harry Fox who was a vaudeville comedian with the Ziegfeld Follies. Another story says that the dance is so named because of the similarity to an equestrian gait that was dubbed the Foxtrot by the military. It is a gait where unlike a normal trot where the front left and rear right (or front right and rear left) legs are moved at the same time causing a somewhat jerky motion, the Foxtrot has the animal moving each leg one at a time making for a smooth trot that is easier on the animal and the rider. Timing: Just as bad posture can blow you right out of the water, if your timing and the music's timing don't match - you lose. It wont matter how well you do anything else. Line: The line refers to the line of your body from head to toe. The line can make or break any ballroom dance. Whether curved or straight, good lines will make you look graceful and elegant. You can find references to the Waltz that go back more than 400 years, however the popularity of the dance had started to wane until 1913 and the advent of the Hesitation Waltz which, as the name implies, slowed the dance down considerably incorporating hesitations and poses throughout the dance. Before the Hesitation, dancing the Waltz was pretty much an endurance test with the couples dancing in one direction then reversing direction when they became dizzy.
