A model field theory, in which the interaction between quarks is mediated by dressed vector boson exchange, is used to analyze the pionic sector of QCD. It is shown that this model, which incorporates dynamical chiral symmetry breaking, asymptotic freedom, and quark confinement, allows one to calculate f_\ensuremathπ, m_\ensuremathπ, r_\ensuremathπ, and the partial wave amplitudes in \ensuremathπ\ensuremath-\ensuremathπ scattering and obtain good agreement with the experimental data, with the latter being well described up to energies E\ensuremath≃550 MeV.
