    Abstract:
    In all microquasars with double peak high frequency QPOs, the ratio of
    the frequencies is 3:2, which supports the suggestion that a non-linear
    resonance between two modes of oscillation in the accretion disk plays a
    role in exciting the observed modulations of the X-ray flux. We discuss
    evidence in favor of this interpretation and relate the black hole spin
    to the frequencies expected for various types of resonances that may
    occur in nearly Keplerian disks in strong gravity. For those
    microquasars where the mass of the central X-ray source is known, the
    black hole spin can be deduced from a comparison of the observed and
    expected frequencies.
