This is the first of a sequence of papers that address the non-perturbativeorigin of the central, and spin-dependent forces between quarks. Its mainthrust is a focus on meson spectroscopy in the center of mass frame. We suggesta "dense instanton ensemble" model for the QCD vacuum, to explain theinterquark forces in mesons, from quarkonia to heavy-light and light-lightones, to the extent it is possible. The sequels will show how to export theseinteractions to the light front, and derive the corresponding Hamiltonians andmesonic wavefunctions.
