We review recent progress in modeling the quark-gluon content of mesons and their low-energy interactions through the Global Color Model field theory. An emphasis is placed on techniques that are shared with the approach based on truncations of the Dyson-Schwinger equations of QCD. In contrast to most other field theory models for QCD degrees of freedom in hadron physics, this approach directly deals with the derived intrinsic space-time extent of the meson modes in their role as field variables and can accommodate confinement as well as dynamical breaking of chiral symmetry. Various theoretical techniques and approximations found useful in this approach are described. Selected applications reviewed here include the properties and interactions of the Goldstone bosons, interaction vertex functions, low energy chiral observables, electromagnetic interactions and form factors, and transition form factors. Some initial considerations of Vector Meson Dominance and pion loop processes are discussed.
