A perturbation method is presented for calculating the frequency modification of stellar oscillations caused by rotation and internal magnetic field. A short-wavelength asymptotic analysis derived from ray theory is also presented. The effects on high-order solar acoustic modes of various hypothetical angular velocity and magnetic field configurations are investigated using both methods of calculation. The asymptotic formulas provide a good estimate for the frequency splitting of five-minute modes when the field and the rotation vary sufficiently smoothly. On the other hand, a localized magnetic field, for example at the base of the convection zone, produces a characteristic oscillatory perturbation to the eigenfrequencies.
