A relativistic many-body calculation for an effective QCD Hamiltonian is reported for exotic and charmed hybrid mesons. The nonexotic \(J^{PC} = 1^{--}\) charmonium spectrum now resolves the anomalous overpopulation of observed \(J/\Psi\) states. The exotic hybrid states are near but above 2 GeV, in agreement with lattice and flux-tube calculations, indicating the recently observed \(J^{PC} = 1^{-+}\) resonances at 1.4 and 1.6 GeV are not hybrids.
