Light curve data from the Kepler satellite on pulsating eclipsing Algol-type binary systems display a peculiar feature: the primary shows preferential excitation of putative pulsation modes with frequencies resonant with the orbital frequency of the binary system. A proposed explanation of this phenomenon is tidal driving of pulsations by the secondary. This paper presents a preliminary calculation of the effects of linear representations of tides on the pulsation frequencies of a polytropic primary.
