The lattice dynamical studies of the metallic glass Ca_{70}Mg_{30} by Bhatia and Singh on their model contained two shortcomings, firstly the electron-ion interaction matrix was wrong and secondly, the numerical value of the bulk modulus of the electron gas was accepted arbitrarily. By modifying the electron-ion dynamical matrix and determining all the model parameters from the experimental data, we made a fresh study of the lattice dynamics of Ca_{70}Mg_{30} and compared it to the earlier studies of Bhatia and Singh and also with experimental phonons.
