We study the effect of melting of well-defined crystal surface within the frame of theory of atomic vibrations in harmonic approximation. We find that for two types of cubic crystal lattice: face centered cubic and body centered cubic, we may expect the existence of pre-melting. It is also shown that the occurrence or absence of surface melting depends strongly on the relaxation of lattice constant.
