What concerns me is eagerness of begginers for such things like colgadas, back sacadas, high boleos and ganchos. OMG why, if they are not able to do proper step back?
Because no one signed up to spend years learning to
walk, which they thought they had been doing since being a toddler. They thought they had signed up to do stuff like DWTS/Strictly - like sacadas, ganchos, boleos - the
sensual stuff. It's no longer a cultural
rite of passage. Nobody signed up to adopt BsAs milonga codigos.
You saw this with the comparable UK programme
Dancing on Ice. Of course everyone could just turn up at an ice rink and immediately do 3-turns, mohawks, choctaws, and, of course, spins are easy whilst death spirals are trivia (you can even give them new, catchy, names to highlight the risk and danger). But, of course, many didn't even make one lap without falling and breaking a leg or arm, or worse. Those who became interested did learn to skate forwards, and backwards. Maybe they progressed to a basic 3-turn, or mohawk. Maybe some even progressed to a turn a counter to do a set-pattern Argentine Tango on ice.
But old style teaching for off-ice AT was similar to that on ice. They learnt elements, and it took months/years of practice until they could convince their teacher they were good enough to attend a milonga (to catch the eye of that girl) without embarrassing their teachers at the practica. Now they just want to
dance. I don't blame them. Many of us went to milongas to dance before we were truly ready or even aware of some of those elements.
So, we wanted to do those things we saw some maestros do, or some stage performance, or DWTS/Strictly - like volcadas, colgadas, sacadas, ganchos, patadas, etc.
Back to
what is tango doing wrong: recruiting and retaining! It's not attracting people through shows, performance, demonstrations, al fresco milongas, etc. (basic advertising!). It's not good at providing 'levels' of milonga, as somewhere to dance suitable for novices, and looks down on beginners/novices turning up at some restrictive milonga with 'advanced' dancers (e.g. encuentro, marathon, or some snooty metropolitan milonga). And it sometimes demands a foreign culture - with some weird justifications in our non-BsAs society.
