As a non 'argentine' dancer I have a question... if everyone is talking about how Arg Tango has 'no steps' and is a 'feeling', then why is everyone constantly debating 'accuracy' and 'authenticity'? If I go to an Arg Tango Milonga, why is there a need for me to do what everyone else is doing? In my ballroom world, there are levels of quality, but at the social level nobody is expected to 'perform'...
No animosity here, just need to know;
Well, it's not totally accurate to say there are "no steps". There is a vocabulary, and most AT dancers know the basic words and phrases of that vocabulary. Think of it like a language... If you know some key words and phrases for the most fundamental things, you might get by as a tourist in a country where that language is spoken. You would have to be able to ask for rudimentary directions, find restrooms, handle currency, etc.
In tango, there ARE steps, and people tend to learn them at roughly the same time in their development. They learn ochos before they learn Molinete (because you have to string ochos together to do a molinete). They learn (hopefully) volcadas before colgadas (because leaning towards each other is inherently safer). They should learn Ocho Cortado before Ganchos and Boleos, but so many don't (sigh). Everyone learns front ochos
far too soon in my opinion. The "cross" (Crusada) is a staple (but for some reason, it gets led poorly by a lot of people)
We call these things "moves" rather than steps because some of them don't involve any actual weight changes or travel on the floor, and also because we are snobs.
If you go to a Milonga and dance "whatever" without using any of the AT vocabulary, you might have a good time, and you might actually find some good followers who are able to follow what you do because they (again hopefully) learned to FOLLOW rather than "recognize" what a leader does. My first teacher/partner has a lot of background in ballroom and he would use "steps" from Foxtrot, Viennese Waltz and American Waltz interspersed with AT "steps" as well as other stuff he made up. Maybe that's why I had to learn to follow from Day 1.
You will get into more trouble with the difference in posture and connection than in using non-AT steps. If you expect the follower to always do a weight change with you and never do one without you, you'll get into trouble since they work independently. If you look for "THE rhythm" that you are supposed to adhere to (such as Fox trot's S,S,Q,Q), you'll see that there isn't one. You can dance slows and quicks however you want. We care about dancing "the beat" but not any standard rhythm pattern. There is also no "basic" step that you return to in between other stuff (such as Rhumba's Forward, Side/Together, Back) Some teachers unfortunately teach a "basic pattern", but the real "basic step is simply walking.
Does that answer your question?
