Abstract
We study string propagation in an exact, stringy, four-dimensional dyo nic black hole background. The exact solutions in terms of elliptic fu nctions describing string configurations in the J=0 limit are obtained by solving the string equations of motion and constraints. By using t he covariant formalism, we also investigate the propagation of physica l perturbations along the string in the given curved background.
