waltz - a quick umm-cha-cha,though you can get slow waltzes too. Romantic.
minuet - also three in a bar, but Classical or Baroque in style. Having seen a Baroque one being danced, I can say that it is the most flirtatious thing I've ever seen
I think you'd be unlucky to get asked courante/sarabande/allemande
gigue - compound time and makes you want to cut a caper...no, not the cookery kind
mazurka - uses a dotted rhythm, three in a bar, and romantic or later in style
polka - fast and skipping two to a bar, romantic or later
Correct me on the last two, anyone, if I'm talking tosh - I can't find my music dictionary and they were off the top of my head...
