The frequencies of B-phase order-parameter modes are calculated with l>1 pairing interactions and all Landau parameters included. The two modes that have been observed are modified by v3 and the l=2 Landau parameters. The corrections from v3 and F2a can explain the observed frequency and temperature dependence of the 2+ mode (real squashing mode). A new mode with J=4, whose frequency depends on v3, v5, and F4s, may be observable in the zerosound dispersion.
