In this talk I shall discuss the properties of linear perturbations of scalar-tensor theories belonging to the Horndeski class of actions whilst evolving on a cosmological background. I will discuss the physical interpretation of five independent functions of time, which are sufficient in order to describe the exact linear dynamics of these models. Finally, I will briefly generalize these result to second-order perturbation theory.
