Properties of inertial modes of Jupiter are investigated for an 
polytropic description of the planet interior. We use the anelastic
approximation to overcome the usual handicap of a severe spherical
harmonics truncation. A powerful iterative solver then allows us to
compute the frequencies of the most promising low-order modes using as
many spherical harmonics as necessary. The induced 
errors of
our model are now within observational limits. A plausible
seismological model of Jupiter might thus be at hand provided the use
of a more realistic description of the planet interior.
