We consider the effect of a canonically normalised scalar ﬁeld degree of freedom on the dynamics of gravity from small to large scales. We show that the effects of modiﬁed gravity can be completely captured by the time variations of the scalar ﬁeld mass and its coupling to matter. This leads to a parameterisation of modiﬁed gravity where local constraints are easy to analyse and large scale structure effects apparent.
