Slow is sultry. Slow gives you time to think about what you’re doing, how you’re moving, how the music and your way of moving make you feel. Slow gives your audience, if you have one, time to savor your movements. Slow=total surrender.
Interestingly, slow does not mean you have to choose music with slow beats. Sometimes moving slowly–or doing quick/quick/slooooooow movements–can be spectacularly beautiful when done to fast music.
