The light curves of many Delta Scuti stars appear variable from cycle to cycle, but this complexity may be only apparent and caused by the interaction of two or more pulsation modes with definite, constant periods. The present analysis of differential photoelectric photometry for the Delta Scuti star DQ Cephei yields two frequencies, 8.0603 and 12.6788 c/d, which adjust well to observations covering a span of 29 years.
