The Gor'kov-Dzyaloshinskii theory of zero sound in anisotropic metals is generalized, and applied to specific metals. The main generalizations are: (a) sufficient conditions for the existence of zero sound are derived without the assumption of weak coupling: (b) examples are discussed in which these
