A study of the CBMP definition written by Howard and Moore is not the same.

On careful reading you will see that they are both right regarding step 5, as gent, of the natural spin turn.

Applying Moore's definition of CBMP, "A term used when the body is not turned, but the leg placed across the front or back of the body, so giving an appearance of Contrary Body Movement" would be quite problematic.

Consider that if we allow our leg to exit CBMP at all during whatever degree of pivot we choose to dance, then the re-establishment of the alleged CBMP "across the body" would be the result of subsequent body rotation after the foot is placed. Many such as Geoffrey Hearn explain it this way, but doing so absolutely flies in the face of the "when the body is not turned" portion of Moore definition, since it is explicitly the turn of the body that causes a leg position that was not originally across the body to subsequently become so.

Or do you plan to overturn the body beyond facing LOD, so that it is actually a little towards DW, before you take the forwards drive of step 5, so that you can claim that the allegedly resulting CBMP is a result of the direction of the step being across the body alignment (consistent with the definition) and not of the body rotating across the direction of the step (inconsistent with the definition). That would escape inconsistency, but do you really want to dance in such a pinched fashion?

The rational reader quickly realizes that the occasionally found notation of CBMP on step 5 (in something derived from Moore's work) is simply in error, most likely confusion resulting from the "held in CBMP" of any degree of pivot employed in step 4.

Hi to all,
I came across the following article about the definition of CBMP, written by the late Arthur Franks, UK, around 1940.

/*
There is still a considerable amount of controversy upon the position of CBMP among leading authorities; some assert that whenever one foot is placed across the body, irrespective of whether there is any turning movement or not, CBMP is attained; others claim that CBMP can take place only when there is no rotary movement whatsoever - for example, in the fourth step of the Cross Chasse when it is followed by a lock step, but not when it is followed by any turning movement

After considerable discussion with anatomist and a professor of dynamics the author has satisfied himself that the former school of thought is theoretically the correct one.

It was awhile before Alex Moore agreed that CBM and CBMP could still be used at the same time on a step.

When the ISTD UK decided to adopt a technique of ballroom dancing, they had a choice of using the slim volume of Moore's (103 pages) technique book, or the book written by Henry Jacques (311 pages.)

The definition written by Henry Jacques on CBMP is as follows:
/*
A position arrived at by the placing of the moving leg slightly across and in front of, or behind, the supporting leg, with or without the use of body turn.
*/

The key to understanding the definition of CBMP is to realize the difference between when the position is achieved due to directional of travel while the body may or may not also be rotating (this is CBMP) and when a position to some degree similar is achieved not by the direction of travel, but instead as a result of rotating the body into the moving leg (this is not CBMP).

The mention of no body rotation in the definition is only that the body rotation cannot be the immediate cause. There are numerous examples in the same books which use that definition of situations in which CBMP is documented to occur on steps which also have CBM rotation. The key is to understand that the CBMP is a result of the pre-existing direction of travel, while the CBM is an independent action occurring during that step - were the dancers to decide not to use CBM (not to turn) they would still be placing that foot in CBMP.

It's useful to think of CBMP as being a "place" on the floor which you can send your body towards and thus cause your foot to land on, and CBM being a "verb" or action of rotating your body as you take a step. This makes it clear that a given step can independently involve neither, either or both.
