| We investigate the implications of large N-c and chiral symmetry for the mass spectra of meson resonances. Unlike for most other mesons, the mass matrix of the light scalars deviates strongly from its large-N-c limit. We discuss the possible assignments for the lightest scalar nonet that survives in the large-N-c limit. | |||
