“Dancers occasionally stumble over the truth, but most of them pick
themselves up and hurry off as if nothing ever happened.”
The standard is the lead rocking forward on his left foot and rocking back on his right. Of course, that is only half the pattern. The lead can make as many even steps as he wishes and then rocks back on his right and then rocks forward with his left. The side rock is just as easy and the lead rocks to his left and then rocks back to his right foot. The other half is rocking to his right with his right foot and then rocking back with his left. Most dancers can enjoy their music very well.

In the Carribean, Spanish, English, French and Dutch territories all have similar dances but with different names. The four count favorite of the Europeans led to the development of the rock step and the slow step. The Rumba combined with the Spanish Bolero became the Son and exported to the rest of the world as Rumba.

Then Arthur Murray decide to use his box step for basic and the Rumba has been screwed up ever since. Fred Astaire used the same box step and Arthur Murray sued him and won. The original was relegated back to the sticks and then reemerged in the forties as the Mambo, but it still maintained the Rock Step for two counts and the slow for two counts.
