A class of Phenomenological models of hadronic systems motivated by QCD that have dual representations as a theory of quarks interacting with gluons and hadrons exchanging mesons are investigated. The model is formulated as a fully relativistic model with a light-front kinematic symmetry. The bare meson wave functions and production vertices are determined by the underlying QCD degrees of freedom and can all be calculated analytically. The bare meson exhibits linear confinement and the mass fall in Regge trajectories. The simplicity of the model facilitates the investigation of sea quark contribution to the meson spectrum and wave functions. The hadronic spectrum, lifetimes, cross section, vertex strength and sea quark effects are calculated using quark masses and one strength parameter.
