I think I am agreeing with you, in part, Belle. I would submit that there are certain notes that are traditionally emphasized in the ballroom genres that beckon the dancer to explore with more power in their movement during that time. However, I don't feel that all songs within a genre lend themselves to such for the dancer. I love waltzes with powerful first beats from the instrumentation, and I love foxtrots with vocalizations that stretch a phrase out over the first two beats, but for me, that might be just my appreciation of certain musical aspects of some songs within genres. And I hate those tangos wherein you can barely hear the first beat in a phrase.
At the same time, I have to admire those excellent dancers who make subtle sounds come to life through movements I'm incapable of.
