Jive is the peppy standard of International rhythm dance that would be closest to American Swing. Jive is somewhat faster with 42-44 bars per minute, while East Coast American Swing is 34-36 bars per minute.
Here is the one dance taken from the American style. American servicemen introduced this form of dance to the English during WW2. The classical English body lines, that are all such a part of International are not necessary in the Jive. In fact, the dance looks wrong if the couple strives for too much styling.
Jive is the most difficult dance to judge because there are only six fundamental figures and the rest of the dance is quite free.
