The mass of tetraquark states of all $qq\bar q\bar q$, $qc\bar q \bar c$, and $cc\bar c \bar c$ quark configurations are evaluated in a constituent quark model, where the Cornell-like potential and one-gluon exchange spin-spin coupling are employed. Three mass-dependent coupling parameters are proposed, and all model parameters are predetermined by comparing the theoretical and experimental masses of light, charmed and bottom mesons.
