In Italy, the mambo became a popular dance at weddings and special events, while the quickstep became the trend in America after World War I. By the 1970's, all of these different dances had made their way to America's ballrooms and dance competitions soon became popular. Today, ballroom dancing is the number one form of dance among adults and is widely covered by the media. Ballroom dance can be elegant and sophisticated (like the Waltz) but it can also be hot, sultry and sexy (like the Tango or Paso Doble), or a good bit of lively fun (like the Fox Trot Jive or Quick Step). Webster defines ballroom dancing as simply "Any of various, usually social dances in which couples perform set moves". The dance moves are smooth and precise as the couple dances in a side to side motion, usually in a circular pattern. The waltz is a very popular dance in weddings and special events and is considered to be one of the most romantic dances. Last but not least, the tango is a dance performed which demonstrates the history behind Argentinean cowboys and their dance partners from centuries ago. Below are some popular song suggestions for weddings and ballroom dances that would be appropriate with them. Two very well-known wedding songs are "Love Me Tender" and "I Can't Help Falling in Love with You," both performed by Elvis Presley. These songs, while traditional at weddings, set the perfect tone for a slow waltz. The Viennese Waltz also requires a good deal of stamina, the equivalent, actually of the amount of energy that would be needed to dance a polka. The Viennese Waltz uses a right turn (natural turn), a left turn (reverse turn) and two change steps that link the moves between the turns. Dancing the line of dance (direction of traffic - turning left at the corners of the dance floor) and rotating in a clockwise direction is the Natural Turn. 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. Hold: Dancing with arms, hands etc., in an incorrect position or breaking a hold at the wrong time will cost you points.
