You have great Aplomb

That statement might sound like an insult, but its actually a compliment.  Aplomb means assurance or poise.  Gail Grant states that "This term applied to the dancer means that he or she has full control of body and limbs with the weight correctly centered during a movement".  I think that most people who appreciate dance can think of a dancer that demonstrated great Aplomb and probably a few that didn't.  This isn't a measurable term, but is more of an aesthetic.  As a viewer you either feel that someone does or does not show poise and control over their movement.  This is something that all dancers strive to have, and that takes a very long time to master.
