*seeking to learn* So I get that a tanda is a set of pieces that "go together" and that traditionally, one dances the entire tanda with the same partner. BUT what are "the rules" by which one is supposed to pick the songs? How do you know when (to quote Sesame Street) one of these things is not like the others? (Aside: Curious about what happens if your partner is abominable and you need to leave in the middle of a tanda, but I bet there's a thread on that, so I'll look.) I'm all for breaking rules, btw. I figure it's probably better for me if I know what they are, first, though.
