  The phonon-like excitations of (anti)-instanton liquid ($\bar II$) due to
adiabatic variations of vacuum wave functions are studied in this paper. The
kinetic energy term is found and proper effective Lagrangian for such
excitations is evaluated.The properties of their spectrum, while the
corresponding masses are defined by $\Lambda_{QCD}$ with prevailing
chromoelectric component, are investigated based on the phenomenology of QCD
vacuum already developed.
