Surface and internal waves in a viscous exponential fluid are considered. Singular and regular solutions are obtained. Regular solutions are a generalization of wave motions arising in the model of an ideal fluid. Singular solutions correspond to ligaments - highly gradient flows. This type of solution arises taking into account the finite viscosity of the liquid. The phase and group velocities of regular movements and their analogues for irregular movements are investigated. All the obtained relations are constructed in physically observable variables - depending on the frequency and wavelength. This type of dependency is more convenient for experimental verification. Complete solutions to the problem of wave propagation in a viscous exponentially stratified fluid are constructed.
