I'm hesitant to use the word "wrong" with a street dance, especially since "jitterbug" seems to encompass several different dances, but a few things come to mind:
- Upwards Pulse: Either that, or they're pulsing downwards before the downbeat instead of after. Lindy is pulsed downwards on or after the downbeat. Ballroom east coast is pulsed upwards, is that what this is?
- Slotted: To my knowledge, hollywood lindy, west coast swing, and maybe 20s charleston are slotted, but this doesn't look like any of those. What is this dance? Is there a type of shag that looks like this?
- No leverage: You don't see any stretch, leverage, tension, etc. There is no shared weight, no rock step, no anchor step.
I think that if you took all of the leverage/anchors out of early 1980s ballroom-style west coast swing, mixed it a little bit with merengue footwork, and then did sidepass variations almost exclusively, you would have something that looked like this.
No swing, no juice, no upper body movement, stepping like a polka dancer, no resistance, no following, no connection, no this, no that, no nothing but steps and pattern.
Now I know why my teacher wanted to hit me over the head with a chair during my most recent lesson. I was dancing like the woman in this clip! And I have the video of my lesson to prove it! <slinks away in shame>
Well, she's starting her "swingout" on her left foot, for one thing. I'm also not sure it's taking 8 counts (sometimes looks more like 5, and sometime 7 or 9, but never really 8).
If swing, salsa, and hustle had a baby with a woman who didn't believe in moving her ankles, this would be it. (How is it possible to dance without ever using the ankles?)
I just wanted to add that Chinese Jitterbug doesn't seem to have any swing [as we usually recognize it] (it's just a name and doesn't mean that we have to classify it as a swing dance). Perhaps a similar dance exists as Korean Jitterbug.
In the future, I think it would be nice when posting videos for discussion, if we could try keep it balanced rather than leaning towards criticism from the onset.
