Abstract We investigate a special concept of quarkhadron duality in meson physics at low and intermediate energies. With a relativistic propagator for confined quarks, we calculated masses and widths of the mesons which areS- andP-wave states ofq¯q (J P=0−, 1−, 0+, 1+c, 2+) as well as meson-meson scattering amplitudes at energies up totrs ≤ 1.3 GeV by including light pseudoscalar and vector mesons into the interaction dynamics. Our investigation shows that the influence of the light meson dynamics resutls in: 1. a contribution to the constituent quark mass of approximately 200 MeV. 2. the appearance of a new soft confinement force barrier responsible for the formation of the highly excited meson states.
