  The model for hybrid excitations of the QCD string with quarks is presented
starting from the perturbation theory in the nonperturbative background. The
propagation of a system containing $q \bar q$-pair and gluon is considered. The
simplified version of the Hamiltonian, including both long-range
nonperturbative interaction and Coulomb force, is derived. The masses of the
lowest $q \bar q g$ hybrids are evaluated, and numerical results for the
spectra are listed.
