This course will introduce some concepts of variations of Hodge structures guided by the example of families of elliptic curves. It will be shown how the Gauss Manin flat connection gives rise to an instance of the tt* equations and of special geometry in this case. The modularity of the solutions of the differential equations stemming from the Gauss Manin flat connection will be discussed. Furthermore a differential ring of special functions will be introduced, whose existence is related to the flatness of the Gauss Manin connection and which is, in the case of elliptic curves, related to the differential ring of quasi modular forms. Moreover, an enhanced moduli space of pairs of elliptic curves together with differential forms will be introduced, which connects in a natural way to modular forms.
