The correlation of the rotational structure of the -bands, with the ground bands, of the even-Z even-N atomic nuclei of the mid mass region is reviewed from the global view point. The variation of the energy level pattern with N and Z in the major shell (, ) is illustrated quadrant-wise, through the moment of inertia plots. The correlations are viewed in terms of the dynamic symmetries of the Interacting Boson Model-1. The average value of the power index of the single term power law of level energies in the -band is compared with the ground band. Its variation with neutron number N is displayed for Dy, Er and Os isotopic chains. The effect of the beta stability line across the quadrants is pointed out. Also the variation of the -band head energy with N and Z and its correlation with ground and -band is analyzed.
