OK got to have my 5 cents worth lol. Dancing On2 is not one beat back, it is dancing on the slap of the conga beat on your break step, the step is accented therefore its more like a slow quick quick type step.
When I was 1st told about dancing On2 and not educated about the conga beat I danced One beat back thinking it was correct belive me you will look like an On1 dancer trying to dance On2
If you dance On1 it is really easy to convert if you know this. Just download yourself a conga beat, listen for the slap which will be when you accent the 2 and 6. The 2 is distinguished from the 6 by the clave majority of the mambo music is on a 2/3 clave and the first beat of the clave is the 2. This again makes the 2 easy to find for someone learning.
The step length is also different small step on 1 what we call the break step which is a slightly longer step on 2,3 then small step on 5 and break step on 6, 7
Preparations for spins happen on counts 7, 67 or 567 depending on style, there are many styles of dancing On2 even different techniques chosen by the New York dancers. Frankie Martinez for example uses different techniques than say Santa Rico
The one thing they do have in common is the timing
Is On2 better LMAO You will hear a lot from On2 dancers that its much more ‘with the music’ Personally I think being with the music depends on how good you are at interpreting it and improvisation through your social dancing, but the one thing it does to for the woman especially is give her different time to add styling,
I’ll explain. In an On1 cross body you step back and fwd 123 fwd on5 turn on 6 small back step for balance on the 7. When you take a cross body On2 as a woman you come fwd on counts 1,2 and are turned by count 3, unless the man is putting you into spins it tends to give you some time on the 45678, which is why quite a lot of ladies prefer it. Whilst when you dance On1 you are putting styling into possibily 123 although as you have to step back there is not as much freedom and maybe you can fit something into 45 as you cross the man.
Although I prefer to dance On2. I have watched advanced competitions where the On1 dancers were better than the On2 dancers, just because they were better interprting the music. When you start to dance On2 the conga beat becomes ingrainned and it becomes not so much fun to dance On1 to certain songs that are predominently mambo songs. Knowledge of the music is key. The best dancers here dance all styles as do I. On1 On2 Mambo and Cuban
ON2
Your cross body AS A MAN is fwd 6 step back out of the line 7 open on 1 lead on 2
Cross body inside turns similarly the basic being to dip the hand on the two bringing it above the ladies head for the start of the turn by count three
You will find that not all your moves are easily transferable from On1 to On2 but that a lot of them are :)
