Acrobatic rock and roll (spelled rock'n'roll by its organizing body, the World Rock'N'Roll Confederation) is a fast, athletic, physically demanding form of partner dance that originated from Lindy Hop but has evolved to a choreographed sport, often done in formal competition.
The most obvious acrobatic feature of this dance sport are its kicks (into thin air) and its gymnastic elements like lifts, jumps, throws and flips.
Because of its demanding technique, high speed, and acrobatics, rock and roll is a straining high-performance dance and is most often performed by young dancers.
Unlike much rock 'n' roll music, the dance puts stress on the first and third beats of each measure.
Current advanced tournament rock and roll dancers wear neither petticoats nor jeans, as the dancers originally did, but rather multicoloured costumes made of elastic artificial fibre, made individually by special tailors.
One reason is that their acrobatic maneuvers have grown more and more dangerous, requiring rugged apparel that still provides freedom of movement.
