When dancing with first-timers, I try to keep to the same moves that were done in the beginner's class (Admittedly, it takes me half the dance to remember them all

) - that's only four moves. Mixing the order of them, changing the timimg subtally, getting them used to a pattern, then leading them into a simple variant. I think that it's more important that they relax so that they can enjoy the dance more.
I with almost everyone else, I experiment and throw different bits of different moves together. Unfortunatly, I don't think that I've had any dances that go exactly how I imagined

But I'm
really good at faking it now

{Honest gov. That was meant to happen - it's a new move I've been working on

}
I think that the first thing to aspire to is 'attitude' - the self confidence that the lady will not walk off in a huff if you only do three moves or screw one up. Just keep dancing. Secondary to this is learning how to lead the lady. Once you have worried enough about these, only then should the number of moves even be considedered.
