Show Dance does not have a specific technique of its own; in a broad sense, show dances are based on ballet, jazz, modern, and contemporary dance techniques. When performing Show Dance compositions, styles from performing arts dance disciplines may be used. Other dance styles, such as Disco Dance, Hip Hop, Popping, Breaking, Tap Dance, as well as acrobatic and gymnastic elements, may also be included and used, but they should not dominate the performance. Show Dance must always have a concept, story, or idea intended to convey a message. The theme should be clear and expressed through dance movements.
