Abstract: The dependence on quark flavour of hyperfine mass separations is studied within the quark flavour number framework for the case of pseudoscalar and vector meson ground states. It is shown that for mesonic partners with at least one beauty valency the flavour dependence with respect to the flavour of the remaining valency differs from the corresponding dependence for partners with at least one nonstrange or at least one strange valency. For partner mesons with at least one charmed valency the hyperfine splittings are almost independent of the other flavour.
