From my background, I want structure and definitions. It all depends on whether it would be possible to determine the fundamental issues around which there could be broad agreement, and then to determine a vocabulary or method by which they could be defined/illustrated.
Well, the first difficulty is, who gets to define these issues, and who gets to agree them? In fact, that's probably the main obstacle.
The other main obstacle, of course, is getting such a syllabus to be implemented and respected.
The current UKA syllabus, for example, I think it's fair to say, is rubbish - it's just a list of steps. Steps are almost irrelevant in the dance, in my opinion.
I believe that AT is built from fundamental elements, and a syllabus that has a page or two of introductory waffle, and then lots of tables illustrating a set of predetermined moves, has got it completely wrong.
Yep - completely agree.
However, another approach could work better, but is unlikely to come out of one of the teaching societies, unless, existing members take up the social dance at a high level, and then write a text themselves, and get it adopted by their peers.
The first problem is that many of the aspects which are fundamental to the dance (improvisation, musicality, connection) are extremely difficult to provide "examinable metrics" on. So there's less business incentive for a dance society to include these aspects in a syllabus.
The second problem is that many of the other theoretically-measurable aspects of the dance are subjective. Posture for example - is Apilado "wrong"? Or embrace - is it "wrong" to lead an ocho in close embrace, or to lead a walk in open?
So what you're left with, as things which can be easily-measured, are, well, a list of steps...
It must be possible to articulate the basic principles of this dance in a form of language that can be shared with others.
To a point, yes. But only to a point, I think. Beyond that you get into "many roads up the mountain" territory.
In many different ways...
Is the lead different in cross system, and if so, how (and why)?
No, and no.
What are the mechanics of an ocho? How is it danced and how was it led?
Lead / follow a pivot, then lead / follow a step
The development of a 'technique' needn't be limiting or prescriptive if it is prepared in the right way and with the right approach. There are lots of ways of doing all sorts of things, but a basic syllabus could aim to illustrate a simple way to dance particular actions that would work for most people, most of the time. Beyond that, comes personal development, individuality and flair, but most of us have those attributes only to a modest extent...
I actually agree that a structured approach is best, and even that some form of standardisation would be useful.
I just don't think it can happen.
