  We study the vibrational modes of Skyrmions with baryon numbers one through
eight in the standard Skyrme model. The vibrational modes are found in the
harmonic approximation around the classical soliton solution and the real parts
of the frequencies of the modes are extracted. We further classify the
vibrational modes into representations of the symmetries possessed by the
Skyrmion solutions. We find that there are approximately 7B low-lying modes for
a Skyrmion with baryon number B, in addition to an infinite continuum of
scattering modes. This result suggests that the instanton moduli space, which
is 8B-dimensional, does not accurately describe the deformation space of
Skyrmions as previously conjectured.
