That's a pretty broad question. Perhaps you could narrow it down a bit. Also, by "syncopated Hustle", do you mean the regular Hustle danced to the counts &123 (or 123&), or is there some sort of specific regional variation called "Syncopated Hustle" I'm not aware of?
Thank you for trying to reply to my question! I am still a beginner, especially in Hustle. During last practice I saw someone doing a syncopated step in hustle. I was trying to repeat, but could not, though it seemed easy. I really do not know the difference between the two counts you mentioned. So, what I want to know is what is the technique to produce this syncopated step. I am sorry if I am still confusing!
Let me try to help by describing the problems I had a few weeks ago when first learning the Hustle.
I found the timing, &123 hard to follow, because I assumed that the "1" in there fitted cleanly on the "1" of a bar (measure) of music. So I assumed that there was a pause on "4". At that point I realized I was doing things more slowly than others.
My next assumption was that I was doing it at half speed, so I tried fitting &123 into 2 beats. That is crazily fast.
Finally after doing some more watching, searching etc, I discovered that the &123 timing uses just 3 beats of music. The next &123 starts straight away. So if we count the beats of three bars as 1 2 3 4 5 6 7 8 9 10 11 12 we dance 4 groups, with timings as &1 2 3 &4 5 6 &7 8 9 &10 11 12
and then we're back on "1".
This is probably why the term "syncopated is used. It's not a normal form of musical syncopation, but the timing moving within bars creates a syncopated feel.
With this explanation, take a look at the hustle clip on dancevision's site and you'll see what I mean.
