  We present an analysis of the dynamics of two-flavour QCD in the vacuum.
Special attention is payed to the transition from the high energy quark-gluon
regime to the low energy regime governed by hadron dynamics. This is done
within a functional renormalisation group approach to QCD amended by dynamical
hadronisation techniques. The latter allow us to describe conveniently the
transition from the perturbative high-energy regime to the nonperturbative
low-energy limit without suffering from a fine-tuning of model parameters. In
the present work, we apply these techniques to two-flavour QCD with physical
quark masses and show how the dynamics of the dominant low-energy degrees of
freedom emerge from the underlying quark-gluon dynamics.
