One thing I've noticed today, after haven't been watching a whole lot of bellydance videos this past weekend/week...
Music dictates your dancing...
It defines how you move.
I feel like (insert belly dancer here) couldn't dance to the same song as (insert different belly dancer here).
Or they could dance to it, but the song wouldn't highlight or compliment what they're good at.
The song compliments how you move.
And that's why when you choose a song to dance to, you feel like you know it, or you get it... Its because you understand it on a different level.
