"If the couple just takes out the slow sensual stuff and puts in quicker feet to keep up with the music, the whole tone of the dance is very different." Exactly! And as far as I can tell this is exactly what happens when the music gets faster. There are other things that can go on in the music that preclude slow and sensual, too. And, there is actually a streching out of a musical phrase, or simply holding a note(s) for a l.. o.. n.. g time that I like a fair amount of "pull" on too. But it's more of a "I am resisting this because I want to stretch out this motion and it takes two bodies working togther to get that feeling" thing.
