There is an incredible relation between bharatanatyam and mathematics. Every movements in bharatanatyam uses the numbers 3 (Thishram), 4 (Chaturashram), 5 (Khandam), 7 (Mishram) and 9 (Sangeernam) in various permutations and combinations for any of the dance compositions. The postures are characterized by linear formations and circular patterns. Certain postures create a wonderful symmetry in the body as in geometry that adds to the beauty of the performance. So it’s very important to understand the straight line patterns, circular movements and about the symmetry formation. A technical excellence in all these aspects could be achieved with years of practice. A combination of good posture, balance, centering symmetry and the geometric correctness gives you ‘Angasudhi ‘. More importantly all these efforts to perfection should be unconsciously executed by the dancer to make the performance impressive.
