Upon his return to England he taught these steps as a completely new dance. It has been suggested that the name Cha-Cha (or Cha-Cha-Cha as it is called by some people) was coined for the sound of the 3 quick steps after the forward and back step (or back and forward steps). The steps for the Cha-Cha are taken on the beats accompanied by a strong hip movement as the leg straightens on the half beat. 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. Over the last 12 years USABDA has promoted the growth of all forms of ballroom dance as well as coming up with a program to establish chapters in each state. They have enjoyed major growth in numbers of chapters, dancers, competitions, workshops and social dances each year. Each year the USABDA sends United States representatives to the World Games. 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.

Three of these points involve the hands, his left hand holding her right, her left hand on top of his right upper arm (for the Tango her hand would go behind his arm) and his right hand on her back resting on her left shoulder blade. The other two points of contact are her left elbow resting on his right elbow and the right side of her chest touching the right side of his chest. American ballroom dresses are typically easy to distinguish from other nationalities. A primary trait of American dresses is that they "flow" much easier than those from other countries. For example, an American ballroom dress usually has at least two layers of skirt, along with other cuts of fabric flowing from the neck and back.
