Use is made of Onsager's hydrodynamic equation to derive the vibration spectrum of the vortex lattice in a d-wave superconductor. In particular the rhombic lattice (i.e. the tilted square lattice) is found to be stable for . Here denotes the critical field at which the vortex lattice transition takes place.
