We first briefly review how we investigate the modes of oscillation trappedwithin the inner region of accretion disks by the strong-field gravitationalproperties of a black hole (or a compact, weakly-magnetized neutron star). Thenwe focus on the `corrugation'(c)-modes, nearly incompressible perturbations ofthe inner disk. The fundamental c-modes have eigenfrequencies (ordered byradial mode number) which correspond to the Lense-Thirring frequency, evaluatedat the outer trapping radius of the mode, in the slow rotation limit. Thistrapping radius is a decreasing function of the black hole angular momentum, soa significant portion of the disk is modulated only for slowly rotating blackholes. The eigenfrequencies are thus strongly increasing functions of blackhole angular momentum. The dependence of the eigenfrequencies on the speed ofsound within (or the luminosity) within the disk is very weak, except forslowly rotating black holes.Comment: Submitted to The Astrophysical Journal. 33 pages, 5 figure
