A unified dispersion relation is derived for linear transverse electrostatic modes in a one-dimensional dust plasma crystal consisting of cold dust particles located at lattice points uniformly spaced in equilibrium. In special limits, this dispersion relation reduces to the transverse shear and lattice modes predicted by earlier generalized hydrodynamic and lattice models in the strong-coupling regime.
