Babamm, that's difficult to say because the terminology is not consistent between the two lists.

I personally would go with the USISTD syllabus.

I think you may be confusing " techn ", with variations .

Techn.in american style is pretty standardised...even the majority of Bronze variations are the same or similar.. the differences start to become more evident in the Silver and up categories, and , even then, much will be similar or same .

Ok, let's say variations then. The technique is the same. Got it!
But what about the different timing in the American Style Rumba. The USISTD book says QQS QQS (in a box step for example) but a lot of people say it's SQQ SQQ. That is a difference or am I wrong? Or is both possible?

The rhythm in rumba has been controversial for many a long yr.

F/A ... QQS

A/M.... SQQ.

In real musical terms emanating from Danzon, QQS would be correct . In comps, you would not be downgraded for your choice ( In Amer. style )

Excuse me, but I don't have a clue about these abbrevations: What do you mean by "F/A" and "A/M"?
Well, I think SQQ is easier to learn. That might be the reason they introduced it long time ago.

Sorry-- fred astaire and arthur murray ( chain schools ).

The reason why different choices were made by both, is one chose authenticity, the other expediency .

which are you referring to authenticty? musically american rhumba should be danced sqq. the break is after the one two there isnt a break on the three four. most schools(with the exception of f/a) are geared toward sqq.

hellohi and others.By counting q q s or s q q. doesn't take into acount that in between the beats there is a space which is 1 (and) or 2 (and). It is on the (and) that we dance. A step is just a step. It is in between the steps that we see the action of the hips. Its only a matter of time before the American style starts to use the International style technique. Why do I say that, because with youtube more and more people will see which is the better action. OK . Fire away.
Whilst we are on Rumba. Google Pattie Labelle On My Own. Click top one it runs for 4.35 mins.

here we go again...you apparently do not know the difference between a " lateral action " and a "figure 8" concept of Cuban motion.

Both techniques were designed and applied accordingly, and are correct for the "style " of dance they are applied to .

Terence. I am well aware that there is a figure eight type action, or if you like to call it an infinity sign. Also the pendulum type swing that is now combined within the figure eight action. A step is still a step. The latin motion is following the step. With th slower music that is now being played. The hips are being used more than at any time before. Some teacher are even on a Basic movement it is being discribed as a type of cucaracha action.
Something I was told by a person who was a pupil of Wally Laird was that at that time Wally was not in favour of a syncopation step in the Cha on anything other than the syncopation on 4 and 1. He said with the music it is not syncopated on for instance 2 and 3. How times have changed.
Theres another story here from Wally's pupil. He arrived for his first lesson. Knocked on the door just before 10 am . Wally answered dressed in a dressing gown. Yes he said... I'm here for my 10 o clock lesson. Young man I have never taken an am. class in my life. You are twelve hours too early.
