Hadron structure advances provided by the Coulomb gauge model are
summarized. Highlights include a realistic description of the vacuum
and meson spectrum with chiral symmetry and dynamical flavor mixing,
accurate hyperfine splittings for light and heavy systems, glueball
and hybrid meson predictions in agreement with lattice QCD, and
tetraquark results providing an understanding of the observed
π1(1400) having unconventional quantum numbers.
