Abstract: The effects of possible resonances between pulsation modes in Cepheid light curves are briefly reviewed. In particular, the possible effects of the resonance P2/P6=2 in nonlinear pulsation models of (hypothetical) second overtone mode Cepheids are discussed. The observational data and the nonlinear models of Cepheids tend to confirm the hypothesis that several simple resonances are at work in Cepheids.
