Bernadette taps a quick rhythm on the polished floor with her heel, then another, and raises an eyebrow at you. "Listen first. Then tap it back. Not what you think it is. What it is. If you are good, I will teach you the one I never teach in class." The studio is empty and the floor is warm. Step in, listen to the count and tap back what you hear. I will tell you the truth about your rhythm.
