Many (who often enjoy Lindy hop) have commented that Modern Jive is not a precise dance.  This article  expresses all the important facets in a form that mathematicians should be proud of (along with a commentary in layman terms and all symbol defined).  Hopefully all misunderstanding should be cleared up.  Enjoy!

Modern Jive = Swing – footwork
Modern Jive + footwork Swing
Swing First Move triple steps + modifications

Take away the footwork from Swing dances and you get the basic form of Modern Jive, however you cannot just add footwork to Modern Jive to get Swing! Indeed, Swing is rather like various kinds of First Move triple-steps.

Modern Jive count = 2 music beats
Typically 120 < beats per minute < 180
Number of clockwise turns/spins number of anticlockwise turns/spins
Palm grip leading a spin
Raised arm leading a turn

    Read as "implies..."

Modern Jive moves contain a minimum of 2 jive counts and can be very long indeed.  Each jive count occurs after every 2 music beats.  Typically, beat rates between 120 and 180 per minute are good for Modern Jive.  Ladies like being unwound after being wound up.  A palm grip is used before a spin and a raised arm before a turn.

Types of move

Airsteps Aerials Drops Dips (Airsteps Dips) Bad back Pain Teaching moves involve footwork groan in audience     Read as "in union with..." ie "or..."

Air steps are just another name for aerials.  Drops are similar to dips.  If you do either and have a bad back, you will experience pain!  When teachers teach moves involving footwork, the result is a groan in the audience.
