N2  - We investigate the role of the tidal charge in the orbital resonance model of quasiperiodic oscillations (QPOs) in black hole systems. The orbital Keplerian frequency and the radial and vertical epicyclic frequencies of the equatorial, quasicircular geodetical motion are discussed, and the local maxima of their radial profiles related to Keplerian accretion discs are given, assuming the inner edge of the disc located at loci of the innermost stable circular geodesic. It is shown, how the tidal charge could influence matching of the observational data indicating the 3:2 frequency ratio observed in GRS 1915+105 microquasar with prediction of the orbital resonance model.
