That depends on how the whole lesson is taught. You might see 'moves', but there can be technique involved in those moves.
Yes. This is something I've become acutely aware of lately, for two reasons:
1. I've started to help a teacher with her classes, and that has taught me that for all of my grumbling about "moves" and sequences being oversold, you can't teach musicality and technique to normal people without pedagogical patterns. You can teach musicality and technique directly to the gifted, sure, but to teach them to Mr. Dragged Here By My Girlfriend and Mrs. I'm 80 And Want To Learn Tango Before I Die – who are more representative of real-world class makeup – you have to pass through movements. Want to teach foot placement, posture, and vals timing? Invent a flashy set of steps that won't work without foot placement, posture, and vals timing, and watch the typical student slowly get it right, thinking, "I'm finally getting this pattern," when reality is that they're finally getting the skills that make the pattern work.
2. I have an abysmal, terrible, no-really-it's-awful memory for sequences. I can see them 20 times and forget everything after the second count. This is why I'm
helping a teacher rather than
being a teacher. Anyway, I recently asked my coaches whether we could go directly to technique and skip the patterns that give me headaches. They explained to me that most technique cannot be taught directly even to the gifted – it needs context. I brought up drills and they were unequivocal: Yes, there's technique that's drillable, but at my level I don't need a coach for that . . . I need a mirror. Technique that needs coaching needs the context of dance.
So, I'm generally skeptical of claims that lessons without "moves" are useful. To which I'll add, "moves" includes walking. Lessons on walking are very useful. When you should start those is a hard call, but my personal experience is "Don't wait more than 4-5 years after starting tango." The catch is finding lessons in walking, because it lacks flash.
