Stellar rotation and magnetism are two phenomena which intervene in many pulsating stars. As a result, calculating their effects on stellar pulsations has been the subject of active research for a number of years, and many results have emerged. For instance, slow stellar rotation lifts mode degeneracy and leads to evenly spaced frequency multiplets. At rapid rotation rates, a new organisation of the frequency spectrum appears, in which the centrifugal force plays a dominant role. Stellar magnetism plays an important role on pulsation frequencies both directly and indirectly. Various studies show how magnetism can shift frequencies and play on mode excitation and selection. Magnetism also introduces other types of waves with a different frequency spectrum organisation.
