The De Gennes and Matricon problem of finding the spectrum of oscillations of massive vortex line under the action of pinning and viscosity forces is solved. The obtained vibration spectrum of the vortex is discussed and the role of each contributing force is elucidated. The trajectory of the vortex motion is calculated and illustrated.
