Could someone familiar with the current ISTD Ballroom Technique say what foot position is given for step 1 (RF) of a Natural Rock Turn, and whether there is any usage of CBM?

I was discussing the evolution of the figure the other day, from Alex Moore's original to the current IDTA definition, and I want to make the comparison.

Thanks

The " evolution " of rock steps in Tango , originate from T/ Arg. where they tend to dance them more linear.

The current DW e.g. with a very slight CBM ( I prefer to teach it with a strong Right shlder/side lead )is much in keeping with the present dance construction... Use 2 opposing corners to set amounts of turn..

Are you finding something in the figure that is contradictory ?

I think you may have answered my question.

Alex Moore's original Ballroom Dancing described (and I'm writing here from memory, not a verbatim quote) that the RF step is danced with CBM, starting to turn to R. [Actually he says RF fwd, turning body to the right]

My rather battered old copy (1986) Revised Technique has that toned down to 'slight' CBM, and no further mention of turn, whereas the current IDTA technique cuts the CBM altogether, and has right side leading (no turn), the standard turn being distributed between steps 1 & 3.

This is an interesting evolution: I was looking for confirmation that the current ISTD technique persists with slight CBM, or does a right side leading now rule the day in both Societies?

Like all changes in standard techn. there will be those that defend the " old ".. thats not to say that they are incorrect ..theory is frequently debatable..

as Scriv. would say.. " techn. is flexible and may change to suit the circumstance " ( thats a paraphrase )..

Yes, but what IS the current ISTD technique?

Another figure that is commonly danced differently from the established technique is the Back Corte. It is charted man LF back with left side leading, but frequently seen danced with slight CBM on 1 (or at least square) and normal CBM on 2, particularly as a follow to a RF Rock, and that makes a much more interesting 'shape', but has no authority in technique.

AS the " book " states... like many figures, there are going to be varying opinions on " execution ".. always wise to stay with standard techniques thru medal test levels..

Good e.g... for many yrs.. 4th step of nat. spin turn was listed as backing LOD ( yet many of the Prof competitors were using a different alignment... the one we use now ) I actually got reprimanded ( many yrs ago ) by an Examiner, for bringing up this matter .

Telemark. Rock Turn. Alex Moore's book gives two alignments which are travelling down the LOD or Diag to wall. Both finish Diag to wall. When I did my first Medal as far as I can remember I did a Rock Turn against the LOD still finishing Diag to Wall. I have always thought that the right side lead was to stop people going into a modified Spanish Drag. I doubt if you will ever see a Rock Turn in a major final anymore.
Alex Moore does say RF forward turning body to the right and is in CBM as is the fifth step. The fifth step can also be in CBMP.
Those books will drive a person to drink. Just take a look at a Reverse Turn in the Foxtrot and compare the differences between the two books on the first two steps. I can't think why it was changed from 3/8 of a turn between 1 and 3. To a 1/4 of a turn between 1 and 2 followed by an 1/8 between 2 and 3. Heaven knows why it was changed. But if you are doing a teaching test you had better come up with the later.
