I´m not quiet sure, if we differ substantially or in the terminology we use (this ahead,
John).
So for me projection belongs to close embrace tango and milonguero style. Show tango mostly depends on push and pull. Projection requires close body contact. The leader conveys information already before the following step, by subtle alignement of his chest.
Leading is not shoving, a follower is not a cart !
No change, we still differ!
Milonguero never was a style, there were many ways of dancing
and a milonguero was an addicted frequenter of the milongas.
We can blame Susana Miller and Cacho Dante for the idea of it
being a style, in truth for them it was a descriptive term for marketing.
And I definitely don't like Cacho Dante's rigid body, stiff armed
way of dancing.
We both have the same idea of what step (or leg) projection is and
I reject that just as many if not all dances do which are danced with only
slow progression. Victor Sylvester called this "crush dancing" in ballroom
which was/is also called rhythm or merely social dancing because the
long striding ballroom dances are themselves anti-social in crowded
conditions just as step projection is in any crowded dance hall.
The most serious problem that this idea of step projection causes
is an inability of the dancers to dance in small spaces but it makes
rhythmical connection unlikely, or difficult at least, because all the
time interval is occupied with movement and weight transfer.
My dance maximises the time spent on one foot and minimises
the time spent on weight transfer. This way of dancing produces
something else entirely - a way of connecting or "feeling" the music.
