My starting point is always to take the people who come to my classes or lessons, and work with them from where they actually are in their individual dance journeys, and frequently that is at the very start. In classes, of course, the scope for truly personal attention is limited, and I think that students understand that.
I doubt if most new dancers have any such idea as usually
they have little idea about anything except the attraction of tango.
Different embraces are part of tango, unless you wish to dance in a particular style or narrow range of styles. If you are an experienced dancer, and are dancing in an area with a well developed tango scene that can satisfy your style preference (and that is all it is, there is no one true path to tango enlightenment), then that is a perfectly reasonable choice for you, but not necessarily for others. You will naturally gravitate to places where your chosen style predominates, or is the norm, and your partners will be self-selecting too. But your experience will only reflect a small part of the totality of tango.
All those different embraces are what help make tango unnecessarily
difficult. Still it keeps people coming back to classes. The totality of tango
as you put it encompasses social, competition and performance.
Life would be easier for many if there was some narrower selection.
Personally, I highly value the development of a personal style that can be enjoyed without superficiality or stilted commonality.
There is a stilted commonality caused by the wide variety of embraces,
positions, views, thoughts and opinions. The preference to accommodate
all the wide variety of embraces seems to result in a very narrow dance;
a subset of the dance which can be done in all the embraces.
Working with a specific embrace might result in a deeper exploration
of all the possible movements within that embrace.
There is a common view in Buenos Aires that tango starts with the embrace
and having experienced the change that the embrace can make I rather tend
to that view now. Abroad, teachers tend ignore the embrace as too difficult,
more or less as you have expressed.
What makes you think I don't encourage students to eliminate basic faults? But if you mean the sort of class where everyone spends three quarters of the time being marched up and down the room, to improve their walk, then no thanks. I don't think that it actually works with a group of people, for a start, but it is also commercial suicide. No one likes doing it (unless they have just paid 3x the going local rate for some visiting maestro's wisdom, and then they will swallow anything rather than believe that they've just been duped), and my experience has been that all that walking empties a class more quickly than anything else could.
No, I am not advocating walking classes nor am I interested in whether
something is commercial suicide but more in what is best for a student
to help progress towards the goal of actually dancing the music of tango.
CBM works in the same way, regardless of whether you walk forwards or backwards. If it results in a swing out, its basic principle has been misunderstood or is being misapplied, coming, as it does, from a completely natural walking action.
I'm inclined to think you don't understand.
CBM is noise capable of interfering with the lady's perception/feel
of the intent of the man. And if she responds in the usual tango way her
backwards projecting leg will aim outward because she will feel a turn.
As a partner dance, the action of one dancer inevitably affects the other. If the leader walks with CBM, the follower must follow (or there is something fundamentally broken about their embrace).
Hmmmm . . . yes . . . . . exactly . . . . . and feel the beginning of a turn.
Or you are teaching her to ignore the turning implication and progress
straight back. No wonder some women won't turn unless they are
specifically lead a giro and guys end up rock-stepping corners much
to the boredom of some of their partners.
There certainly is CBM in tango, but you may choose not to employ it. It needn't be so marked as to be obviously visible, and many things in tango can only be observed with difficulty, but are readily felt.
The extent of CBM if any is not to transmit it in the upper body
so reality it amounts to mild disassociation.
Classes are the preferred way of learning in most dance styles for most people, and the majority will never take privates, even if it would be of benefit to them. Teaching in a group environment therefore forms a significant proportion of the contact time of many teachers. Most teachers enjoy teaching group classes and few would accept your premise. Apart from anything else, teachers cannot dictate how students choose to learn, or how much time, effort and money they are prepared to devote to their learning. It is another aspect of taking people as they actually are.
No, it is an aspect of commercialised teaching. Regularly take a little money
off a lot of students keeps them coming back for, or for as long as
you can maintain the illusion of learning. A never never instalment plan
on the basis that they will never learn enough to break free from the
yoke of supposed learning.
Teachers choose what they do and some can indeed be dictatorial.
Classes can result in prescriptive teaching, of course, but so can any other teaching strategy - that depends on the teacher. Any competent teacher should recognise that the members of any group (and a couple is a group of two) have individual needs and a range of learning styles. If I ever thought that faced with a mixed group comprising waddlers and non-waddlers, I would have to sacrifice one in favour of the other, it would be time to find something else to do for a living.
There's plenty of prescriptive teaching in tango, usually out of the
necessities of attempting to teach disparate groups. I don't believe
that you can be any better than a whole host of other teachers who
attempt the same thing. They may have different solutions but usually
it results in too many generalisations to be useful or is prescriptive
of style or teaches a narrow range of movement or as a last (sometimes
first) resort teaching moves, the classic solution to group teaching.
Of course we approach this from different perspectives, you as a
commercial teacher seeking to teach tango as a means of helping
to earn a living from dance while I am a past student, no longer being
frustrated by the spurious claims and unsatisfactory learning experiences.
