We review chiral symmetry breaking at the BCS level, in the framework of chiral invariant quark models and in the Schwinger-Dyson formalism. We revisit the {pi} mass problem beyond the BCS level. We show a theorem on the masses, on the widths and on the qq-bar content of the scalar mesons {sigma} and f{sub 0}.
