Although they probably all had some influence on the modern Waltz, at some point the Landler's hopping movement became more of a gliding motion, which is why the Landler more than the others, is sometimes considered the forerunner of the modern Waltz. In the early 19th century the popularity of the Waltzen rose to such a great degree that several large dance halls were opened to accommodate the crowds. When it comes to the competitive dances there are two groups, Combi (one partner is in a wheelchair the other is not) or Duo (both parties are in wheelchairs). They learn all the Standard Ballroom dances and the Latin American Ballroom dances. For those who are just interested in social dancing they offer courses for line and solo dances. By 1927 the jumpiness was gone and the steps were smooth and gliding and the dance was now referred to as a Slow Foxtrot. This ballroom dance is composed of walking steps and side steps. When on a crowded dance floor like in a night club short steps are used. For ballroom dancing long, smooth, easy gliding steps combine to give the Fox Trot its unhurried appearance. Poise: In smooth dancing, the stretch of the woman's body upwards, outwards and leftwards into the man's right arm will achieve balance and connection with his frame, as well as to project outwards to the audience. Poise like posture and line has everything to do with the image you project as you move around the ballroom. 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. By the end of the decade Xavier had the best Latin American orchestra of his day. Monsieur Pierre Lavelle, a London dance teacher, and his partner Doris Lavelle were responsible for bringing and popularizing the Rumba and other Latin American dances to Europe. There are many different dances and versions of ballroom dancing. Each of these unique dances has specific steps and characteristics that make it different from other dances - but there is one aspect that remains constant throughout each style of dancing. No matter what dance style is being performed, you can bet they are being performed by a couple.
