While historically ballroom dance may refer to any form of formal social dancing as recreation, with the eminence of dancesport in modern times the term has become much narrower in scope, usually referring specifically to the International Standard and International Latin style dances (see dance groupings below). In the United States, two additional variations—"American Smooth" and "American Rhythm"—have also been popularized and are commonly recognized as styles of "ballroom dance".
The term "ballroom dancing" is derived from the word ball, which in turn originates from the Latin word ballare which means "to dance". In times past, ballroom dancing was "social dancing" for the privileged, leaving "folk dancing" for the lower classes. These boundaries have since become blurred, and it should be noted even in times long gone, many "ballroom" dances were really elevated folk dances.
Tap dance is a form of dance in which the shoes worn by the dancer, known as tap shoes, are used as percussive instruments. The percussive sounds are made by metal "taps" on the heel and toe of each shoe.
Debbie Allen (born January 16, 1950 in Houston, Texas) is an American actress, choreographer, director, and producer. She first began receiving critical attention in 1980, when she appeared in the role of Anita in the Broadway revival of West Side Story which earned her a Drama Desk Award.
She is probably best known for her role as Lydia Grant in the hit 1982 TV series Fame. During the opening montage of each episode, Ms. Grant told her students: "You've got big dreams? You want fame? Well, fame costs. And right here is where you start paying... in sweat." Allen was also lead choreographer for the film and television series, winning two Emmy Awards and one Golden Globe Award.
