Jive
Jive is in 4/4 time running about 200 BPM (Beats per Minute).
It is a spot dance derived from Jitterbug (Swing Music Dance)
However, its not unusual to dance it to Rock'n'roll.
Probably because Rock was endemic in the 1950's when British Ballroom competitions added Ballroom Jive .
Expect less hopping and more knee pumping action. (If it hurts don't do it).
Try to put in plenty of chassis.
Jive was originally a way of parodying the speech patterns and dancing of Blacks.
It began with the Minstrel Shows in the South when whites in Black Face put on Variety Shows.
