It seems when people talk about modular forms they tend to forget that they are very related to families of elliptic curves. Here I want to explain some simple way to understand the connection. We will consider modular forms for the full modular group $SL(2, \mathbf Z)$.

So consider the simplest family of elliptic curves, the Weierstrass family:

$y^2=x^3+ax+b.$
