Abstract
The thermal and quark/baryon chemical potential dependences of quark condensate and masses of $Ï$- and $Ï$-mesons are studied in the instanton model of the QCD vacuum in precritical region. The impact of phonon-like excitations of instanton liquid on the characteristics of $Ï$-meson in such an environment is also examined.
