A compound drop composed of viscous Newtonian core and shell fluids is disturbed away from its motionless spherical state. The physical characteristics of the drop determine the decay rates of any disturbance. This damping process is accompanied by out‐of‐phase displacements of the two interfaces. Special limiting cases of a thin and thick shell are investigated.
