Keep your shoulders relaxed and in a normal position, not raised. Relax your hands and pretend like you are wearing finger cymbals by bringing your middle finger down and your thumb in towards your middle finger. This will give your hands a more graceful appearance. Make sure you have energy in your finger tips. Imagine a string holding up your wrists so that your hands are not limp.
Balance is achieved by ever-shifting adjustments of weight distribution.
Weight distribution is critical in this dance. When a dancer is off-balance, she is greatly restricted from moving advantageously. A person is on balance when his or her physical organization provides the greatest number of possibilities for movement in a particular situation. Basically, if your feet are both flat, your weight should be evenly distributed between your two feet. However, if one foot is on the ball and the other flat, the flat foot is carrying the majority of the weight and the foot on the ball is for balance.
